Description

Technical Field

[0001] The present invention is an automatic wallpaper pasting machine for applying paste to wallpaper to be pasted on the ceiling or wall surface of a room. Specifically, in the case of pasting while attaching a cut tape or an underlay tape to the paste surface of the wallpaper, it is a wallpaper pasting machine having a function for facilitating the operation for an operator to wind the cut tape or the underlay tape around a narashi roller.

Background Art

[0002] Conventionally, in interior construction, for a wallpaper to be pasted later onto a wallpaper already pasted on a wall, at the end on the side of the previously pasted wallpaper, when pasting with a wallpaper pasting machine, it is known that it is possible to work neatly by pasting a cut tape on top of the paste and peeling it off when pasting the wallpapers together. Cut tapes and underlay tapes for this purpose are sold, and wallpaper pasting machines are equipped with a cut tape device for mounting the cut tape and the underlay tape. Also, the types of cut tapes and underlay tapes include those wound in lengths of 1000 m and 500 m, and those with thin and thick thicknesses are sold. Also, among wallpaper pasting machines, there are manual wallpaper pasting machines in which an operator rotates a plurality of rollers by pulling the wallpaper by hand, and automatic wallpaper pasting machines in which a plurality of rollers are rotated by a motor.

[0003] Using FIGS. 10 and 11, a case of pasting wallpaper while attaching a cut tape or an underlay tape in a conventional automatic wallpaper pasting machine (101) will be described. The cut tape C and the underlay tape are set in a cut tape mounting device composed of a cut tape mandrel (166), a pair of left and right side plates (167) that can be attached through the cut tape mandrel (166), and a paper tube holding portion (168) that abuts against the inside of the cut tape paper tube to hold the cut tape, and are mounted on the leg portion (104). The cut tape C and underlay tape are pulled out at the front, hooked onto the bottom of the glue box (107), rise along the front, wrap around the leveling roller (114), and are attached to the back edge of wallpaper A where glue B has been applied, and are discharged together with wallpaper A.

[0004] Do not apply adhesive B to the side of cut tape C that is not attached to the adhesive surface of wallpaper A.

[0005] Furthermore, the widthwise setting position of the cut tape C is such that it adheres to the edge of the wallpaper A to which adhesive has been applied. Therefore, if the width of the wallpaper A cut by the slitter (106) is wide, the cut tape C is set closer to the outside of the leveling roller (114), and if the width is narrow, it is set closer to the inside.

[0006] Also, if you want to replace cut tape C with a different type, you need to remove cut tape C, replace it with the other cut tape C, and then reassemble the set. In this case, since it is not possible to rotate only the leveling roller (114), the worker opens the upper frame (102), disconnects the leveling roller (114) from the gears of the other rollers, and rotates only the leveling roller (114) while being careful not to shift the position of wallpaper A, to clean the adhesive adhering to the area around the leveling roller (114). This is done every time the cutting width of wallpaper A is changed.

[0007] Furthermore, the leveling roller (114) and the glue cutter are integrated into a single leveling roller assembly which is detachably attached to the main body (101a). [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Patent No. 5334009

[0009] [Patent Document 2] Japanese Patent Publication No. 2021-24218 [Disclosure of the Invention] [Problems that the invention aims to solve]

[0010] If the width of wallpaper A is narrowed after several sheets have been glued and then cut by a slitter (106), the worker must move the cutting tape C inward so that it adheres to the edge of the narrowly cut wallpaper A, and then wipe off the glue B that has adhered to the surface of the leveling roller (114) that was in contact with the wider wallpaper A and leveling it, using a water-soaked sponge. At this time, if the position of the wallpaper A in the transport path of the main body (101a) is shifted, wrinkles will occur, or the position of the leading edge of the wallpaper A to be glued next will change. Therefore, the upper frame (102) must be tightened, and while the measuring roller (108) and the feed roller (109) are holding the wallpaper A, the wallpaper A hanging down in front of the main body (101a) must be lifted up so that the leveling roller (114) is visible, and the glue B around the entire circumference of the leveling roller (114) must be wiped off. However, since the leveling roller (114) does not rotate, it is difficult to wipe off the glue B around the entire circumference.

[0011] Also, if you replace the cut tape or underlay tape with a different one after gluing several pieces together, The worker is manually lifting the leveling roller assembly, which has glue on it, and wrapping cut tape or underlay tape around the leveling roller. Therefore, there is a need for a wallpaper pasting machine that makes it easy to clean the area around the leveling roller with a sponge or similar material when moving or replacing the cut tape C, and that facilitates the process of winding the cut tape onto the leveling roller. [Means for solving the problem]

[0012] The wallpaper is transported by a feed roller. The adhesive is applied using an adhesive roller to form the adhesive surface. A wallpaper pasting machine that pastes and discharges a cut tape or an underlay tape onto a pasted surface while leveling the pasted surface with a spreading roller, The spreading roller is structured such that a one-way clutch is fitted into a hole of a spreading roller gear for rotating the spreading roller, and a shaft of the spreading roller is inserted into and attached to a hole of the one-way clutch, By the motor When the feeding roller rotates in the direction of discharging the wallpaper, The spreading roller gear and the shaft of the spreading roller are connected to rotate the spreading roller in the direction of discharging the wallpaper, With the motor stopped spreading roller Add the obtained force Trying to rotate When doing, The shaft of the spreading roller and the spreading roller gear are idled to rotate the spreading roller, The wallpaper is ejected in the direction of the discharge. characterized by rotating.

[0013] A bearing plate for pivotally supporting the spreading roller on the main body is provided, By fitting the bearing plate into a notch of the main body, The spreading roller is pivotally supported on the main body removably, characterized by this.

[0014] The bearing plate has a guide portion for winding a cut tape or an underlay tape around the spreading roller, characterized by this.

[0015] The guide portion is provided below the spreading roller and has an inclined surface with an upward slope from the downstream to the upstream of the wallpaper conveyance path, characterized by this.

[0016] The wallpaper is conveyed by a feeding roller, Paste is applied by a pasting roller to form a pasted surface, A wallpaper pasting machine that pastes and discharges a cut tape or an underlay tape onto a pasted surface while leveling the pasted surface with a spreading roller, The leveling roller is installed by fitting a one-way clutch into the hole of the leveling roller gear that rotates the leveling roller, and then inserting the shaft of the leveling roller into the hole of the one-way clutch. By the motor If the feed roller rotates in the direction of ejecting the wallpaper, The leveling roller gear and the leveling roller shaft are connected, and the leveling roller is rotated in the direction in which the wallpaper is discharged. With the motor stopped leveling roller Add The power that was obtained Trying to rotate If you do so, The shaft of the leveling roller and the leveling roller gear are allowed to rotate freely, and the leveling roller Wallpaper is directed towards the discharge direction Since it is characterized by rotation, If you need to narrow the width of the wallpaper to which you are applying the adhesive midway through the process, With the top frame still closed, peel back the hanging wallpaper. leveling roller by hand rotate While doing so, you can wipe away any adhesive residue from the surface. Furthermore, at this time, all roller gears except the leveling roller are engaged, but only the leveling roller is free-spinning. Therefore, the wallpaper inside the main body is held in place by all rollers except the leveling roller and does not move. Therefore, even when the motor is stopped, The operator can easily wipe the entire circumference of the leveling roller.

[0017] A bearing plate is provided to support the leveling roller on the main body. The bearing plate fits into the notch in the main body, The leveling roller is detachably supported on the main body, The worker can lift the leveling roller by hand to create a gap, allowing them to wrap the cutting tape around the leveling roller. Additionally, the leveling roller can be removed from the main unit and washed with water.

[0018] The bearing plate is characterized by having a guide portion for wrapping cut tape or underlay tape around the leveling roller, If you replace the cut tape attached to the cut tape dispenser with a different type, If you push the leading end of the cut tape into the gap between the guide and the leveling roller, The cutting tape emerges upwards, surrounding the leveling roller along the guide section. The operator can easily wrap the cut tape around the leveling roller.

[0019] The guide section is located below the leveling roller and is characterized by having an inclined surface that slopes upward from downstream to upstream along the wallpaper transport path. The cutting tape emerges upwards, surrounding the leveling roller along the guide section. The operator can easily wrap the cut tape around the leveling roller. [Brief explanation of the drawing]

[0021] The configuration of the automatic wallpaper pasting machine (1) of the present invention will be explained using Figure 1 and Figure 2. The automatic wallpaper pasting machine (1) consists of a main body (1a), legs (4), a slitter (6), and a control device (5). The main body (1a) consists of a pair of left and right upper frames (2) and a pair of left and right lower frames (3), and the upper frames (2) can be opened and closed relative to the lower frames (3) by opening and closing pivot points. The lower frame (3) is pivotally supported by a feed roller (9), a doctor roller (11), a gluing roller (12), and a leveling roller (14). Furthermore, a glue box (7) is mounted between the left and right lower frames (3), and a glue lifting roller (15) is provided inside the glue box (7) for scooping up glue B and transferring it to the glue application roller (12). Furthermore, a slitter (6) is attached to the lower frame (3), which is equipped with a pair of upper blades (28) and a pair of lower blades (29) for cutting the left and right edges of wallpaper A.

[0022] Furthermore, the upper frame (2) is pivotally supported by a measuring roller (8), a high-tension roller (10), and a press roller (13), and a measuring section (35) is provided at the shaft end of the measuring roller (8).

[0023] Next, we will explain the gears used to rotate each roller, using Figures 4 and 5. Figure 4 shows the left side of the main unit (1a) (the left side from the perspective of the person applying the adhesive), and wallpaper A is fed in from the left side of Figure 4 and discharged to the right side. (The side from which wallpaper A is fed in is called the upstream side, and the side from which it is discharged is called the downstream side.) Figure 5 shows the right side of the main unit (1a) (the right side from the perspective of the person applying the adhesive), and wallpaper A is fed in from the right side of Figure 5 and discharged on the left side. The right side of Figure 5 is the upstream side. As shown in Figure 4, the motor gear (51) meshes with the large-diameter gear (52a) of the first intermediate gear (52), and the adhesive roller left gear (53) meshes with the small-diameter gear (52b) of the first intermediate gear (52). The rotational drive source of the automatic wallpaper pasting machine (1) of the present invention is a motor (24), and the gear that transmits the drive is a motor gear (51) attached to the output shaft (24a) of the motor (24).

[0024] As shown in Figure 4, the left gear (53) of the adhesive roller and the doctor roller gear (54) mesh together.

[0025] As shown in Figure 4, the doctor roller gear (54) and the feed roller gear (55) mesh together.

[0026] As shown in Figure 5, the right adhesive roller gear (56), which is attached to the right shaft of the adhesive roller (12), meshes with the fifth relay gear (60), and the fifth relay gear (60) meshes with the leveling roller gear (61). The leveling roller gear (61) is attached to the leveling roller shaft (82) via a one-way clutch (89).

[0027] As shown in Figure 5, the right gear (56) of the adhesive roller meshes with the second intermediate gear (57), the second intermediate gear (57) meshes with the third intermediate gear (58), the third intermediate gear (58) meshes with the fourth intermediate gear (59), the fourth intermediate gear (59) meshes with the lower blade right gear (63), and the lower blade right gear (63) meshes with the upper blade right gear (62).

[0028] An adhesive roller drive gear (not shown), mounted inside the lower frame (3) of the adhesive roller (12), meshes with an adhesive roller gear (not shown) mounted on the adhesive roller (15).

[0029] The measuring roller (8) and the high-tension roller (10) do not have gears attached to transmit the driving force of the motor (24).

[0030] Next, the role of each roller will be explained. The feed roller (9) is a roller that holds wallpaper A between the measuring roller (8) and the feed roller (9) and transports the wallpaper A. The feed roller gear (55) shown in Figure 4 rotates clockwise, and the wallpaper A set in the roll receiver (19) shown in Figure 1 is pulled out, cut in the width direction by the upper blade (28) and lower blade (29) of the slitter (6), and then transported into the main body (1a).

[0031] The adhesive roller (12) is a roller for applying adhesive. The rotation of the adhesive roller (12) and the adhesive top roller (15) draws up the adhesive B stored inside the adhesive box (7) and transfers it to the surface of the adhesive roller (12). A predetermined thickness of adhesive B, determined by the gap between the doctor roller (11) and the adhesive roller (12), is applied to the back of the wallpaper A by the adhesive roller (12), forming an adhesive surface which is then transported downstream.

[0032] The leveling roller (14) is a roller used to level the adhesive surface and is located downstream of the adhesive roller (12). The leveling roller (14) rotates in contact with the back surface of the wallpaper A, leveling the adhesive surface before the wallpaper A is discharged. In Figure 5, the leveling roller gear (61) rotates counterclockwise to level the adhesive surface and convey the wallpaper A.

[0033] Furthermore, the measuring roller (8) and the high-tension roller (10) are pivotally supported on a pair of left and right upper frames (2), and are rollers that press down on the wallpaper A, and when the upper frames (2) are opened by the worker, the rollers move away from the wallpaper A. Furthermore, the measuring roller (8) also plays a role in generating a measuring signal (37) by rotating in accordance with the conveyed wallpaper A.

[0034] Furthermore, since the fifth relay gear (60) is attached to the upper frame (2), if the upper frame (2) is opened by an operator, the engagement between the gluing roller right gear (56) and the leveling roller gear (61) is broken.

[0035] Furthermore, the arrangement of the rollers that contact the wallpaper A with the rotational drive transmitted by the motor (24) is such that the feed roller (9) is furthest upstream, followed by the gluing roller (12), and the leveling roller (14) is furthest downstream, with the leveling roller (14) having the fastest peripheral speed relative to the wallpaper A.

[0036] Next, the functions of the control device (5) of the automatic wallpaper pasting machine (1) of the present invention will be explained using the block shown in Figure 3.

[0037] The motor (24) is a DC brushless motor and has the function of detecting the rotor position using a Hall element and outputting a signal proportional to the rotation direction and rotation speed.

[0038] The motor control unit (34) controls the speed of the motor (24) using signals proportional to the rotation direction and rotation speed output from the motor (24).

[0039] The display and operation unit (30) is for inputting operating conditions, outputting operating status, and issuing operating instructions for the automatic wallpaper pasting machine (1), and consists of multiple key switches, an LCD display, a touch panel, etc. A buzzer (not shown) is also provided to generate operation sounds and notification sounds.

[0040] The memory unit (32) is a RAM and ROM that stores multiple processes to be executed by the arithmetic unit (33), and stores data such as variables necessary for executing the processes, operating conditions, and glued execution records.

[0041] The measuring unit (35) generates a measuring signal (37) that is proportional to the rotation of the measuring roller (8) which rotates in accordance with the conveyed wallpaper.

[0042] The cross detection unit (36) detects the presence or absence of wallpaper A.

[0043] The communications unit (31) is responsible for sending and receiving data with mobile terminal devices and the like.

[0044] The calculation unit (33) mainly consists of a single-chip microcontroller and controls the automatic wallpaper pasting machine (1) by executing a predetermined sequence. It counts the measurement signals (37) generated by the measurement unit (35) and calculates the "actual pasting length" of the transported wallpaper A. Each time the calculation unit (33) counts a measurement signal (37), it adds a parameter t as a counter, t←t+1, and calculates the "actual pasting length" L as L=t×P, (where P is the distance the wallpaper A traveled when one measurement signal (37) is counted (a constant determined based on the diameter of the measurement roller (8))). Furthermore, the calculation unit (33) has the function of controlling the display operation unit (30), the motor control unit (34), the communication unit (31), and so on.

[0045] The leveling roller assembly (81) will be explained using Figures 6 and 7. The leveling roller assembly (81) consists of a leveling roller (14) and a pair of left and right bearing plates (83). An inner glue cutter stay (86), to which multiple inner glue cutters (88) are attached, is detachably mounted on the bearing plates (83). Furthermore, an outer glue cutter stay (85) to which multiple outer glue cutters (87) are attached is detachably and rotatably mounted on the shaft (82) of the leveling roller (14) by an arm (84), and the outer glue cutter stay (85) can rotate around the shaft (82) of the leveling roller (14) (Figure 9(b) shows the position rotated upward, and Figure 9(a) shows the position where gluing is performed).

[0046] Furthermore, as shown in Figure 7, the bearing plate (83) fits into a notch (3a) provided in the lower frame (3), and the leveling roller assembly (81), including the leveling roller (14), is detachably pivotally supported on the main body (1a).

[0047] Figure 8 will be used to explain the details of the leveling roller (14). The leveling roller (14) consists of a one-way clutch (89) and a leveling roller gear (61). The shaft (82) of the leveling roller (14) is mounted by passing it through a hole (89a) in the one-way clutch (89), and the one-way clutch (89) is mounted by fitting it into a hole (61a) in the leveling roller gear (61). The one-way clutch (89) and the leveling roller gear (61) are attached to the shaft (82) of the leveling roller (14) which is on the right side when the leveling roller assembly (81) is fitted into the notch (3a) of the lower frame (3) of the main body (1a). When the leveling roller (14) is pivotally supported on the main body (1a), the leveling roller gear (61) meshes with the fifth intermediate gear (60).

[0048] The orientation in which the one-way clutch (89) is attached to the shaft (82) of the leveling roller (14) is such that, in the automatic wallpaper pasting machine (1) of the present invention, the leveling roller (14) rotates in the same direction as the direction in which the wallpaper A is discharged (forward direction) to level the adhesive surface. Therefore, when the rotational drive from the motor gear (51) is transmitted to the feed roller gear (55) by the meshing of the gears shown in Figure 4, and the feed roller (9) rotates in the direction in which the wallpaper A is discharged, the fifth relay gear (60) shown in Figure 5 rotates clockwise, causing the leveling roller gear (61) to rotate counterclockwise, and the leveling roller gear (61) and the shaft (82) of the leveling roller (14) are connected by the action of the one-way clutch (89). The leveling roller (14) does not spin freely, but follows the rotation of the leveling roller gear (61) and rotates in the direction in which wallpaper A is discharged.

[0049] On the other hand, with the motor (24) stopped, If the leveling roller attempts to rotate due to the force applied to it, the leveling roller (14) will spin freely, causing it to rotate in the direction from which the wallpaper A is discharged.

[0050] By installing the one-way clutch (89) in this way... When the control device (5) of the automatic wallpaper pasting machine (1) is rotating the motor (24) to perform pasting, all of the above shown in Figures 4 and 5 gear The rollers mesh together so that all the rollers rotate, and when the control device (5) has finished gluing one sheet of wallpaper and stopped the motor (24), the worker can manually move the leveling roller (14) rotate When this is done, use a light force to apply the leveling roller (14) rotate It can be made to do so, and the leveling roller (14) rotate While being forced to do so, all of the following are shown in Figures 4 and 5. gearThe rollers remain engaged, and all rollers except the leveling roller (14) (feed-out roller (9), high-tension roller (10), doctor roller (11), gluing roller (12), press-down roller (13), leveling roller (14), and gluing roller (15)) do not receive rotational driving force, the wallpaper A does not move, the measuring roller (8) which rotates in conjunction with the wallpaper A does not rotate, and the measuring signal (37) is not generated, so that the stopping position of the wallpaper A is maintained at the position when the control device (5) finishes gluing one sheet of wallpaper and stops the motor (24).

[0051] Next, the guide portion (83b) provided on the bearing plate (83) for guiding the leading edge of the cut tape C will be explained using Figures 8 and 9. Figure 8 shows the leveling roller assembly (81) attached to the main body (1a), viewed from the side from which the wallpaper A is discharged (the front side of the automatic wallpaper pasting machine). The guide portion (83b) is a projection that protrudes from the lower side of the hole (83a) in the bearing plate (83) toward the center of the automatic wallpaper pasting machine (1), and is provided so as to surround the shaft (82) of the leveling roller (14). As shown in Figure 9, the guide section (83b) is a horizontal surface (83c) from directly below the leveling roller (14) to the front, while the guide section (83b) is a curved surface (83d) behind the leveling roller (14) (upstream side), and the curved surface (83d) is an uphill curve from front to back. The guide section (83b) is an inclined surface located below the leveling roller (14) that slopes upward from the downstream (wallpaper discharge side) to the upstream (wallpaper roll side) of the wallpaper transport path.

[0052] The purpose of shaping the guide portion (83b) in this way is, as shown in Figure 9(b), when the leading edge of the cut tape C is passed through the gap between the shaft (82) of the leveling roller (14) and the horizontal surface (83c) of the guide portion (83b) from the front side of the automatic wallpaper pasting machine (1) and pushed backward, the leading edge of the cut tape C moves along the horizontal surface (83c) behind the shaft (82) of the leveling roller (14), then comes into contact with the curved surface (83e), changes direction upward while following it, and then emerges above the shaft (82) of the leveling roller (14), so that the guide portion (83b) acts to cause it to wrap around the leveling roller (14).

[0053] Next, we will explain how to apply adhesive to wallpaper A while attaching cut tape C using the automatic wallpaper pasting machine (1) of the present invention. As shown in Figure 2, the cut tape mounting device consists of a cut tape core rod (66), a pair of left and right side plates (67) that can be attached by passing them through the cut tape core rod (66), and a paper tube holding part (68) that abuts against the inside of the cut tape paper tube and holds the cut tape C. The paper tube holding part (68), which is fitted into the inner part of the paper tube of the cut tape C and holds the cut tape C, is passed through the cut tape core rod (66) and attached so as to be rotatable, and is sandwiched between the pair of left and right side plates (66) and fixed with wing nuts (not shown) and attached to the leg part (4).

[0054] Then, the worker pulls out the leading edge of the cut tape C, hooks it onto the bottom of the glue box (7), raises it along the front, passes it through the guide section (83b) of the leveling roller assembly (81), and wraps it around the leveling roller (14).

[0055] Next, the worker puts glue B into the glue box (7), instructs the motor (24) to start, all the rollers rotate, and glue B adheres to the surface of the gluing roller (12).

[0056] Next, the operator pulls the lead end of wallpaper A from the roll, opens the upper frame (2), sets it on the adhesive roller (12), closes the upper frame (2), instructs the motor (24) to start, and all the rollers rotate to transport wallpaper A. The cut tape C adheres to the back side to which adhesive B is applied, and is discharged from the front of the automatic wallpaper pasting machine (1) and hangs down.

[0057] With the preparation work now complete, the operator then sets the "set adhesive length" and "set number of sheets" of wallpaper A to be glued using the number keys and set keys on the display operation unit (30), and presses the start key. The calculation unit (33) then starts the motor (24) to rotate the feed roller (9) and other rollers. The wallpaper A set in the wallpaper roll receiver (19) is then pulled out between the feed roller (9) and the measuring roller (8), and its side edges are cut by the upper blade (28) and lower blade (29) of the slitter (6) to a predetermined width, and then it is transported into the main unit (1a). The calculation unit (33) counts the measurement signals (37) generated by the driven rotating measuring roller (8) on the conveyed wallpaper A and calculates the "effective gluing length".

[0058] Adhesive B is picked up by the adhesive roller (15) and transferred to the adhesive roller (12), and is applied to the back of wallpaper A to a predetermined thickness by the gap between the doctor roller (11) and the adhesive roller (12). The back of wallpaper A, to which adhesive B has been applied, is smoothed with a leveling roller (14). The cut tape C, which is wrapped around the leveling roller (14), adheres to the back of the wallpaper A to which adhesive B has been applied, and is discharged together with the wallpaper A.

[0059] The calculation unit (33) stops the motor (24) when the "execution gluing length" reaches the "set gluing length". The worker places a utility knife along the top surface of the leg stay (27) and cuts the wallpaper A, to which the cut tape C is attached, in a straight line, completing the first piece of adhesive wallpaper. Repeat the same process to create multiple sheets of pre-pasted wallpaper.

[0060] Then, if the width of the wallpaper A to which adhesive B is applied needs to be narrowed midway through the process, the worker narrows the width of the left and right upper blades (28) and lower blades (29), narrows the width of the left and right cutting tape attachment devices, and with the upper frame (2) closed, lifts up the hanging wallpaper A as shown in Figure 9(b), and then uses the leveling roller (14) by hand. rotate While doing so, wipe off any adhesive B that is adhering to the surface.

[0061] At this time, the gears of all rollers other than the leveling roller (14) (feed roller (9), high tension roller (10), doctor roller (11), gluing roller (12), press roller (13), leveling roller (14), and gluing roller (15)) are engaged, but due to the action of the one-way clutch (89), only the leveling roller (14) rotates freely. Therefore, the wallpaper A inside the main body (1a) is held by all rollers other than the leveling roller (14) and does not move. Also, since only the leveling roller (14) rotates freely, the worker can move the leveling roller (14) with light force. rotate It can be made to happen.

[0062] The worker wipes off the adhesive B adhering to the surface, moves the cut tape C to that spot, and then applies adhesive to the remaining wallpaper A.

[0063] Furthermore, if the cut tape C attached to the cut tape attachment device is replaced with a different type midway through the process, rotate the outer adhesive cutting stay (85) as shown in Figure 9(b), If you push the leading end of the replaced cut tape C into the gap between the guide portion (83b) below the bearing plate (83) and the leveling roller (14), the cut tape C will follow the guide portion (83b). The leveling roller (14) has a protruding upper part that surrounds the leveling roller shaft (82), so the worker wraps it around the leveling roller (14). Then, adjust the mounting position of the cut tape attachment device so that the position where the cut tape C is wrapped around the leveling roller (14) is at the edge of wallpaper A. Then, apply adhesive to the rest of wallpaper A.

[0064] Once all the wallpaper A has been glued, the worker removes the leveling roller assembly (81) and the leveling roller from the main body (1a) and washes it with water. [Explanation of Symbols]
