Description

[Technical field]

[0001] The present invention relates to a wallpaper pasting machine that pulls in a sheet-like wall covering material (hereinafter also referred to as "cloth") to be affixed to an indoor wall surface or the like from the rear side of the pasting machine body while continuously applying glue to the rear side of the material. In particular, the present invention relates to a wallpaper pasting machine that is capable of folding up the legs with a roll of cross-cut tape still set in it, even with a small pasting machine body. [Background technology]

[0002] Currently, the application of wall coverings to interior walls in the interior construction of buildings is generally done by continuously applying glue to sheet-shaped wall coverings using a dedicated wallpaper pasting machine at the interior construction work site. The general configuration of this wallpaper pasting machine is that the main body of the pasting machine, which is mainly composed of an upper structure and a lower structure with multiple rollers inside, is placed on a base supported by legs, and while the cloth sandwiched between the upper and lower structures is transported by the rollers, the glue is scooped up from the glue tank by a glue pick-up roller journaled in the glue tank and transferred to the glue roller, which then applies it to the back of the cloth.

[0003] Wallpaper pasting machines are available in manual and automatic types, and in one example of a specific configuration, a cloth unwound from a roll of raw cloth is placed on the lower structure with its tip hanging down over the front of the main body, and the upper structure is closed, with the cloth sandwiched between specified rollers between the lower and upper structures. In manual wallpaper pasting machines, an operator holds the tip of the cloth in his or her hand and pulls it forward, causing some of the rollers to rotate in response and causing other rollers to rotate interlockingly via gears. In automatic wallpaper pasting machines, the shaft of a specified roller is typically connected to a drive source such as an electric motor and rotated, causing the other rollers to rotate interlockingly via gears (see, for example, Patent Document 1).

[0004] Fig. 8 is an explanatory diagram showing the internal structure of a conventional automatic wallpaper pasting machine. As shown in the figure, in the upper structure 140 that constitutes the pasting machine main body 110, there are an upper pinch roller 141 that constitutes a pinch roller for taking the cloth into the pasting machine main body from the rear side, a drive roller 143 that applies tension to the cloth C to send it forward toward the front of the pasting machine main body, and a presser roller 142 that presses the cloth C from above between the upper pinch roller 141 and the drive roller 143 and rotates following the movement of the cloth C. These are supported by the side panels of the upper structure 140 so that they are arranged parallel to each other at a predetermined interval.

[0005] Also, within the lower structure 130 which also constitutes the main body 110, the following are journalled on the side plates of the lower structure 130 so as to be arranged parallel to each other at a specified distance from each other: a lower pinch roller 132 which forms a pinch roller in a pair with an upper pinch roller 141, a sizing roller 131 which applies the sizing liquid in the glue tub 150 to the back surface of the cloth, a doctor roller 133 which comes into contact with the sizing roller 131 to adjust the amount of glue, and a levelling roller 134 which, together with the drive roller 143, gives the cloth an appropriate tension and sends it forward.

[0006] Usually, among these rollers, all those arranged in the lower structure 130 are interlocked via gears. On the other hand, among those arranged in the upper structure 140, the drive roller 143 is interlocked with the gear system of the lower structure 130 via gears, and the upper pinch roller 141 and the pressure roller 142 come into contact with the cloth C being transported from rear to front by the rotational drive of the other rollers, and rotate following it due to surface friction.

[0007] In the gluing operation using a wallpaper pasting machine with such a configuration, first the upper structure 140 is opened relative to the lower structure 130, the tip of cloth C is pulled out from the original cloth R journaled at the rear of the pasting machine main body 110 and passed through a slitter 170 attached to the rear of the pasting machine main body via two tension bars, the cloth is then placed on the lower pinch roller 132, pasting roller 131 and leveling roller 134 so that the tip hangs down towards the front of the main body, and the upper structure 140 is closed to sandwich the cloth. A cloth receiving plate 180 inclined forward is installed below the front of the pasting machine main body 110, with a hook piece protruding laterally from the upper edge spanning between the legs supporting both sides of the pasting machine main body.

[0008] With the cloth C set in this manner, the glue pick-up roller 151 is driven by a drive control device (not shown) equipped with a drive motor, and via a gear, scoops up the glue in the glue tub and transfers it to the gluing roller 131. The glue transferred to the surface of the gluing roller 131 is adjusted to a predetermined amount by the doctor roller 133, and then transferred and applied to the back surface of the cloth that is sent to the top of the gluing roller 131 via the pressure roller 142.

[0009] The glued cloth C is then pulled under tension by the drive roller 143 and the smoothing roller 134, the glue surface is smoothed by the smoothing roller 134, and the cloth C with glue on its back side is sent out to the front of the main body. At this time, a core rod is placed at the center of the axis of a roll 189 of cross-cut tape, which is also called "curing tape" or "underlay tape" and is necessary when performing the "overlap cutting" construction method, and the roll is attached to the bottom of the gluing machine main body and laminated on one or both sides of the cloth C.

[0010] [Patent Document 1] Japanese Patent Application Publication No. 5-193300 Summary of the Invention [Problem to be solved by the invention]

[0011] In recent years, small wallpaper pasting machines that can be mounted on small, maneuverable vehicles have become popular. On the other hand, recent cross-cut tapes have become larger, with longer rolls becoming mainstream. Therefore, in the case of small wallpaper pasting machines, the legs are narrow, and it is necessary to fold them up for transportation, remove them, and then reattach them when using them. As mentioned above, in the case of machines that place the axis of the tape roll on a core rod, when placing the roll on the axis of the tape on the core rod that is installed extending from the side of the wallpaper pasting machine toward the center, it is necessary to clamp the tape itself between a pair of side panels so that it does not come loose and fall off the core rod, which makes handling such as installation and transportation cumbersome.

[0012] In addition, cross-cut tapes are commercially available in a variety of widths, such as 60 mm, 50 mm, 45 mm, 38 mm, 35 mm, and 25 mm, and in order to properly adhere tapes of different widths, alignment is required. As mentioned above, handling the cross-cut tape when sandwiched between a pair of side panels is cumbersome.

[0013] The present invention aims to provide a wallpaper gluing machine equipped with a cross-cut tape holder that can slide in the longitudinal direction of the gluing machine body, thereby allowing the cross-cut tape to be moved to match the cutting position of the slitter.

[0024] In the present invention, the wallpaper pasting machine includes a pasting machine main body that moves a sheet-like wall covering from the rear of the main body along a predetermined path by a plurality of rollers that are driven to rotate in conjunction with each other, while continuously applying glue from a glue tub to the back side of the wall covering by a glue roller and discharging the glue to the front of the main body, and a base part with a pair of foldable legs that supports the lower part of the pasting machine main body, and includes a cross-cut tape holder that supports a roll of cross-cut tape that is laminated by pasting along the edge of the pasted wall covering, and the cross-cut tape holder is slidable in the longitudinal direction of the pasting machine main body.By being slidable in the longitudinal direction of the pasting machine main body, the cross-cut tape can be slid to the cutting position of the slitter to paste the cross-cut tape.

[0025] That is, by arranging the cross-cut tape holder that holds one cross-cut tape so that it can slide in the longitudinal direction of the gluing machine body, in the conventional case where the axis of the roll of cross-cut tape is arranged on the core rod, it is necessary to clamp the tape itself between a pair of side plates so that it does not come loose and come off the core rod, which made handling troublesome, but by making the cross-cut tape holder itself slidable in the longitudinal direction of the gluing machine body, the tape does not come loose, making operation easier and enabling various innovations.

[0026] That is, the cross-cut tape holder preferably comprises a mounting plate stretched across the short side of the gluing machine body, a rotating part rotatably attached to the underside of the mounting plate, and a pair of hanging members for hanging a roll of cross-cut tape attached to the underside of the rotating part, the roll having shaft parts at opposing positions for supporting a cylindrical shaft hole part of the roll of cross-cut tape from both sides, and the rotating part is rotatable between a gluing position where the winding direction of the roll of cross-cut tape is parallel to the short side of the gluing machine body, and a folding position where the winding direction of the roll of cross-cut tape is parallel to the long side of the gluing machine body and does not touch during the folding process of the legs. This provides the advantage that the cross-cut tape can be mounted on a small vehicle with the legs folded while still set, without removing the cross-cut tape.

[0027] For this reason, even a small wallpaper pasting machine that can be mounted on a maneuverable small vehicle can easily visit several interior construction sites in a day. In other words, by rotating the holder that holds the roll of cross-cut tape, the roll of tape can be rotated so that it does not hit the legs when folding the legs, which has the advantage that the cross-cut tape can be mounted on a small vehicle with the legs folded while still set, without having to remove it.

[0028] The cross-cut tape holder of the wallpaper pasting machine of the present invention may comprise a mounting plate spanning the short side of the pasting machine body, a rotating part rotatably attached to the underside of the mounting plate, and a pair of hanging members for suspending a roll having opposing axles that support from both sides the cylindrical shaft hole of the roll of cross-cut tape attached to the underside of the rotating part, thereby supporting the roll of cross-cut tape at the bottom of the wallpaper pasting machine.

[0029] In addition, since the cross-cut tape roll is suspended by a pair of suspension members on the underside of the rotating part, there is a rotating part above the roll. Therefore, compared to conventional cross-cut tape rolls that are attached to the bottom of the gluing machine body by a core rod that matches the axis of the roll, the tape does not fray due to wind, etc., and this has the advantage of being easier to handle.

[0030] Currently, the cylindrical core hole of commercially available cross-cut tapes is mainly 38 mm, but there is also a 25 mm one. It is possible to devise a way to hold tapes of two diameters by attaching and detaching an adapter to match these two types of tapes with inner diameters. In a preferred embodiment, the cylindrical core hole of the roll of cross-cut tape is supported from both sides via an adapter having a diameter larger than the diameter of the shaft parts attached to the shaft parts provided at opposing positions of a pair of hanging members of the cross-cut tape holder.

[0031] That is, by setting the diameter of the shafts at the opposing positions of a pair of hanging members to a size that can accommodate the inner diameter of the shaft core of a 25 mm tape, and the diameter of the adapter to a size that can accommodate the diameter of the core of a 38 mm tape, tapes of two different diameters can be used. When tapes of other diameters are released, if the diameter is 25 mm or more, a different adapter can be used to allow the use of the new tape. Also, when tapes of diameters smaller than 25 mm are released, this can be accommodated by reducing the diameter of the shafts of the hanging members themselves and providing an adapter that can hold a 25 mm tape and an adapter that can hold a 38 mm tape.

[0032] As mentioned above, cross-cut tapes are commercially available in a variety of widths, such as 60 mm, 50 mm, 45 mm, 38 mm, 35 mm, and 25 mm. These various widths may be adjustable with a single touch. In other words, a preferred embodiment is one in which the distance between a pair of hanging members of the cross-cut tape holder can be changed to each of the widths.

[0033] More specifically, as shown in the examples described later, a T-shaped locking piece is formed on the rotating member side as the rotating part of the hanging member to prevent the hanging member from falling, and a rail-shaped groove is formed on the rotating member to hold this T-shaped locking piece. On both sides of the T-shaped locking piece of the hanging member, a pair of locking pieces are formed to be locked in locking grooves formed opposite both wall parts formed on both outsides of the rail-shaped groove of the hanging member via slit grooves.

[0034] A knob is formed on the outside of each pair of hooks of each hanging member, and by pinching the knobs inward, the pair of hooks will be released from the hook groove and can move along both walls of the rotating member. The hook groove has seven slit grooves so that the width can be selected with one touch from 60mm, 50mm, 45mm, 38mm, 35mm, and 25mm.

[0035] In the present invention, the cloth is preferably cut to a predetermined width with a slitter and then glued, and cross-cut tape is applied to the glued surface of the side of the glued cloth up to a length equivalent to the height of the interior wall. Therefore, in a preferred embodiment, the cross-cut tape holder is made slidable in the longitudinal direction of the gluing machine body, so that the cross-cut tape can be applied in accordance with the cutting position of the slitter.

[0036] More specifically, as shown in the examples described later, the cross-cut tape is held in place by a mounting plate that is slidably mounted across the upper edges of the longitudinal axes facing in the short direction of the base portion that supports the lower part of the gluing machine body, so that the cross-cut tape can be applied in accordance with the cutting position of the slitter.

[0037] In another wallpaper pasting machine of the present invention, a tape guide for guiding both sides of the unwound cross-cut tape is provided on the front surface of the pasting machine body or base, and the tape guide has a hook piece portion that is hooked onto the front surface of the pasting machine body or base, and a slide piece portion that is slidably held relative to the hook piece portion. The guide piece that guides one side of the cross-cut tape formed on one side of the hook piece portion in the longitudinal direction of the pasting machine body, and the slide piece portion Hook piece Since the tape guide is provided with a guide piece for guiding the other side of the cross-cut tape formed in a position opposite the first guide piece, it is possible to slide and reliably guide cross-cut tapes of various widths. EXAMPLES

[0038] 1. Overall configuration of the automatic wallpaper gluing machine Fig. 1 is a front view of an embodiment of the automatic wallpaper pasting machine of the present invention. Fig. 2 is a side view including a cross section of a portion of the automatic wallpaper pasting machine of Fig. 1. Fig. 3 is a side cross section of the main body of the automatic wallpaper pasting machine of Fig. 1. As shown in Figs. 1 to 3, the automatic wallpaper pasting machine of this embodiment comprises a pasting machine main body 1, a base part 15 on which the pasting machine main body 1 is placed, and legs 2 composed of a front leg 21 and a rear leg 22 arranged in a pair at the front and rear of the lower left and right ends of the base part 15 in order to support the pasting machine main body 1 at a predetermined height.

[0039] The main body 1 and the base 15 are fixed with snap locks 16 that are respectively hooked onto two hooks on the lower side walls of the gluing machine main body 1. The base 15 and the pair of legs 2 are provided with a folding mechanism that allows the left and right legs 2 to be folded so that they face each other, and a cover 23 is formed at the folded portion between the base 15 and the legs 2. The bottom of this cover 23 is formed with a grounding part 24 that comes into contact with the ground when folded.

[0040] The gluing machine main body 1 is composed of a lower structure 3 mainly consisting of a glue tub 5, and an upper structure 4 placed on top of it so as to be able to open and close. A controller 6 is attached to the lower structure 3 on one side panel 11, and a removable slitter 7 is disposed on the rear side of the lower structure 3. The upper structure 4 is disposed so as to cover the upper part of the lower structure 3.

[0041] As the gluing roller 31 rotates due to the drive shaft of the drive source (not shown) in the controller 6, the other rollers to which the rotational motion is transmitted via gears also rotate, transporting the cloth C, one end of which has been unwound from the roll R sandwiched between the upper and lower structures 4 and 3, from rear to front. As the cloth C is transported over the gluing roller 31, the glue pulled up from the glue tub 5 is transferred and applied to the back surface of the cloth.

[0042] The gluing roller 31 is supported by pivot plates on both left and right side walls of the lower structure 3, and is configured to be positioned as low as possible into the glue tub 5. The glue in the glue tub 5 is removed by a glue up roller 51 that comes into contact with the gluing roller 31. The glue up roller 51 is supported by pivots on both sides of the glue tub 5 at a position closer to the rear than the center, and scrapes up the glue in the glue tub 5 as it rotates and transfers it to the gluing roller 31.

[0043] The gluing roller 31 is connected to the drive shaft of a controller 6 equipped with an electric motor, which is a drive source, detachably attached to the gluing machine main body 1. The rotation shaft of the gluing roller 31 is linked via gears to the rotation shafts of predetermined rollers among the lower pinch roller 32, doctor roller 33, and leveling roller 34 arranged in the lower structure 3, and the upper pinch roller 41, pressure roller 42, and drive roller 43 used as length inspection rollers arranged in the upper structure 4.

[0044] As shown in Figure 3, the smoothing roller 34 has multiple claws attached approximately evenly in the longitudinal direction by spacer members to guide the glued cloth C sent through the smoothing roller 34 to the front of the gluing machine main body 1.

[0045] In addition, on both sides of the wallpaper pasting machine, there is a lever that drives an eccentric gear that is eccentrically fixed to the rotating shaft of the doctor roller 33. This lever moves the shaft end of the doctor roller 33 held by the eccentric gear relative to the pasting roller 31, changing the relative distance between the doctor roller 33 and the pasting roller 31, making it possible to adjust the amount of paste adhering to the pasting roller 31.

[0046] A cloth receiving bracket 25 is rotatably disposed on the pair of left and right legs 2, and a cloth core rod 26 passing through the center of the original roll R is supported at the tip of the cloth receiving bracket 25.

[0047] Wall covering material (cloth) C unwound from the original roll R is conveyed to the slitter 7 while being bent by a first tension bar 61 installed below the slitter 7 and a second tension bar 62 installed on the rear leg 22, and both side portions of the cloth C are cut off. The cloth, the back side of which has been coated with glue by the gluing roll of the gluing machine main body 1, has the tape unwound from the cross-cut tape roll arranged below the gluing machine main body 1, and the tape is affixed to the back side of the side portion of the cloth C via a cross-cut tape holder 80 installed in front of the gluing machine main body 1, and is discharged from the front onto a cloth receiving plate (not shown).

[0048] 3, the leg second tension bar 62 is attached by forming leg tension bar holders 27, each of which has a U-shaped groove formed diagonally downward toward the rear and a guide ridge protruding from the center, at opposing positions on the rear leg 22, and fitting the guide ridge into guide grooves (not shown) formed at both ends of the leg second tension bar 62. This second tension bar 62 makes it possible to apply good tension.

[0049] The slitter 7 is mounted in a mounting opening that is opened in the upper rear wall surface of the lower frame of the lower structure 3 of the gluing machine main body 1. The slitter 7 has a guide surface portion 72 disposed in the center of the rear back surface, and cutter box sets 71, each equipped with a rotary blade that rotates at high speed and a motor that drives the blade, are disposed on both ends of the guide surface portion 72 so as to be slidable in the directions of both ends.

[0050] On the guide surface 72 side of the slitter 7, a tension bar support 73 is provided on the side wall of the slitter, which supports a tension bar 74 that presses the cloth transported on this guide surface 72 against the guide surface 72. This tension bar support 73 has the tension bar 74 attached to one end, and is provided at the other end with a fulcrum (not shown) that allows the tension bar to swing between a pressing position and a release position.

[0051] 2. Cross-cut tape holder 1 Figure 4 is a perspective view of the cross-cut tape holder attached to the back of the main body of the automatic wallpaper pasting machine in Figure 1, with Figure a showing the state when pasting and Figure b showing the state when the legs are folded. Figure 5 is a structural diagram of the cross-cut tape holder in Figure 4. On the underside of the pasting machine main body 1, cross-cut tape holders 80 for holding rolls 89 of cross-cut tape are provided on both sides of the pasting machine main body 1 in the longitudinal direction.

[0052] More specifically, the cross-cut tape holder 80 comprises a mounting plate 81 slidably mounted on the upper edge portions of the longitudinal axes opposed in the short direction of the base portion 15 which supports the lower portion of the gluing machine main body 1, a rotating member 82 as a rotating portion attached to the underside of the mounting plate 81 so as to be rotatable at least 90 degrees, and a pair of hanging members 83 which support from both sides the cylindrical shaft hole portion of a roll 89 of cross-cut tape attached to the underside of the rotating member 82 and suspend the roll 89.

[0053] Incidentally, the cylindrical core hole of the cross-cut tape roll 89 is mainly 38 mm in inner diameter, but there are also some with an inner diameter of 25 mm. Adapter 84 can be attached and detached to hold tapes of two diameters in accordance with the tapes in these two core hole parts. That is, hanging member 83 is formed with cylindrical holding part 85 that pivotally supports roll 89 from both sides of the 25 mm core hole part and holds it while suspending it, and adapter 84, which can be inserted into and held in the 38 mm core hole part, is inserted into holding part 85 to accommodate this.

[0054] Furthermore, the distance between the pair of hanging members 83 and the rotating member 82 is changeable between the rotating member 82 and the hanging member 83. More specifically, a T-shaped locking piece 86 is formed on the rotating member 82 side of the hanging member 83 to prevent the hanging member 83 from falling, and a rail-shaped groove is formed in the rotating member 82 to hold the T-shaped locking piece 86. On both sides of the T-shaped locking piece 86 of the hanging member 83, a pair of locking pieces are formed to be locked in locking grooves 87 formed in opposition to both wall portions formed on both outer sides of the rail-shaped groove of the rotating member 82 via slit grooves.

[0055] A knob piece 88 is formed on the outer side of the pair of hook pieces of each hanging member 83, and by pinching the knob pieces 88 inward, the pair of hook pieces are released from the hook groove 87, and become movable along both walls of the rotating member 82. The hook groove 87 has seven slit grooves formed so that the width can be selected with one touch from 60 mm, 50 mm, 45 mm, 38 mm, 35 mm, and 25 mm.

[0056] 3. Cross-cut tape holder 2 Fig. 6 is an explanatory diagram of another cross-cut tape holder, Fig. 6 is an exploded perspective view, Fig. 6 is a perspective view of one of the hanging members and the holding member, and Fig. 6 is an exploded perspective view of Fig. 6. The cross-cut tape holder 90 of this embodiment, like the cross-cut tape holder 80 shown in Fig. 4, comprises a mounting plate 91 slidably hung on the upper edge portions of the longitudinal shafts facing each other in the short direction of the base portion 15 supporting the lower portion of the gluing machine main body 1, a rotating member 92 as a rotating portion attached to the underside of the mounting plate 91 so as to be rotatable at least 90 degrees, and a pair of hanging members 93 that support the cylindrical axial hole of the roll of cross-cut tape attached to the underside of the rotating member 92 from both sides to hang the roll.

[0057] The mounting plate 91 and the rotating member 92 are configured such that the rotating member 92 is attached to the inside of a pair of circumferential members 91a that are aligned along opposing positions on a portion of the outer periphery of the rotating member 92, and four screws are screwed into the pair of circumferential members 91a, so that the edges of the screw heads prevent the rotating member 92 from falling off the mounting plate 91.

[0058] Regarding the rotating member 92 and the hanging member 93, the distance between the pair of hanging members 93 is changeable. More specifically, a T-shaped locking piece 96 is formed on the rotating member 92 side of the hanging member 93 to prevent the hanging member 93 from falling, and a rail-shaped groove is formed in the rotating member 92 to hold the T-shaped locking piece 96. On both sides of the T-shaped locking piece 96 of the hanging member 93, a pair of locking pieces are formed to be locked in locking grooves 97 formed opposite both wall portions formed on both outer sides of the rail-shaped groove of the rotating member 92 via slit grooves.

[0059] Similarly to the cross-cut tape holder 80, a pair of hook pieces of each hanging member 93 has a tab 98 formed on the outside thereof, and by pinching the tabs 98 together inward, the pair of hook pieces are released from the hook groove 97, allowing them to move along both walls of the rotating member 92. The hook groove 97 has seven slit grooves formed so that widths of 60 mm, 50 mm, 45 mm, 38 mm, 35 mm, and 25 mm can be selected with one touch.

[0060] The cross-cut tape holder 90 of this embodiment also has a holding portion 95 on each of the pair of hanging members 93 so that it can hold tapes with two types of axial hole portions, an inner diameter of 38 mm and an inner diameter of 25 mm. The holding portion 95 is made up of a small adaptor 94a that is attached to the axial hole portion with an inner diameter of 25 mm, and a large adaptor 94b that is attached to the axial hole portion with an inner diameter of 38 mm. The axial portion of the large adaptor 94b is attached to the tubular axial portion of the small adaptor 94a and integrated to form the holding portion 95. The tip portions of the axial portions of the small adaptor 94a and the large adaptor 94b are tapered from the tip toward the enlarged diameter portion as a hook portion, and four rows of slits are formed evenly from the tip of the axial portion toward each adaptor portion.

[0061] To integrate the small adapter 94a and the large adapter 94b, the axial core of the large adapter 94b is fitted into the tubular axial core of the small adapter 94a. At this time, the hook portion at the tip of the axial core of the large adapter 94b is inserted into the axial core of the small adapter 94a while shrinking in diameter, and the tip reaches the inside of the adapter portion of the large adapter 94b, the hook portion expands, the small adapter 94a and the large adapter 94b are integrated, and the holding portion 95 is formed.

[0062] Next, the relationship between the hanging member 93 and the holding portion 95 will be described. The through hole 93a of the hanging member 93 is connected to an expanded diameter through hole 93b for separation above it. A border is formed around the periphery of the approximately semicircular through hole 93a, and the thickness of the border matches the length of the axial core portion between the adapter portion and the hook portion of the small adapter 94a. Therefore, at the position of this through hole 93a, the hook portion at the tip of the axial core portion of the small adapter 94a cannot be removed.

[0063] On the other hand, the edge of the approximately semicircular expanded diameter through hole 93b for separation has a taper on both the front and back sides that tapers toward the center position. This taper allows the hook portion at the tip of the axial core portion of the small adapter 94a to taper when it enters or exits the expanded diameter through hole 93b for separation, enabling it to be attached or removed.

[0064] Between the through hole 93a and the separation enlarged diameter through hole 93b, there is a movable piece 93c that can move outward from each through hole, and the small adapter 94a attached in the separation enlarged diameter through hole 93b can be moved to the through hole 93a, or the small adapter 94a at the through hole 93a position can be moved to the separation enlarged diameter through hole 93b and locked in that position. The large adapter 94b can be attached to the small adapter 94a at either the through hole 93a or the separation enlarged diameter through hole 93b position.

[0065] 4. Tape Guide Fig. 7 is an explanatory diagram showing the configuration of a cloth tape tape guide that guides a cloth tape to the front of the automatic wallpaper gluing machine in Fig. 1, Fig. 7a shows two components that make up the tape guide, and Fig. 7b shows the two components combined. As shown in the figure, the cloth tape tape guide 100 comprises a hook piece 101 that is hooked onto the front of the gluing machine main body 1, and a slide piece 106 that is held slidably relative to this hook piece 101.

[0066] The hook piece 101 has a generally rectangular outer shape and is provided with a hook portion 102 on its upper side for hooking onto the upper edge of the glue tub 5 of the gluing machine main body 1, and a guide portion 103 on one side perpendicular to the upper side for contacting one side of the cloth tape. An H-shaped hole 105 is formed in the center of a generally rectangular plate portion 104 on which the hook portion 102 and the guide portion 103 are formed, and the upper and lower sides of the hole 105 are recessed from the surface of the plate portion 104.

[0067] The slide piece 107 of the slide piece 106 enters the H-shaped cutout 105, and the guide portion 108 of the slide piece 106 on the opposite side can hold the cloth tape at any width together with the guide portion 103 of the hook piece 101. [Explanation of symbols]
