[0009] However, the cutting blade 1 for adhesive tape disclosed in Patent Document 1 has a blade 4 due to protruding upwards from the end face 5 of the cutting blade portion to form the blade 4, so when cutting, the adhesive tape 2 drawn out along the plate surface of the steel plate 3 is drawn toward the In the state where the protruding burrs pierce the blade 4, it is torn downward, and the adhesive tape 2 is cut according to the protruding shape of the blade 4 caused by the burrs.
[0010] Thus, although the cutting edge end face 5 is in a straight shape, the adhesive tape 2 is cut in a concave-convex shape corresponding to the shape of the burr-causing blade 4, and sometimes cannot be cut in a straight line.
[0011] In addition, since the blade 4 protrudes upward due to the burr, the blade may be touched due to inadvertence, and the safety is low.
[0012] In addition, since the adhesive tape 2 is pulled downward and the adhesive tape 2 is torn under the condition that the blade 4 pricks the adhesive tape 2 due to the upward burr, the adhesive tape 2 is torn along the burr at the beginning of the cutting by the blade 4a. The direction of cracking, so there is a situation that cannot be cut along the width direction
[0013] In particular, in the case of a non-adhesive wide adhesive tape such as food packaging film or aluminum foil, there are cases where it cannot be cut at right angles to the longitudinal direction (that is, along the width direction). Therefore, the cut tape piece is Inappropriate shape, the cutting end of the tape 2 becomes slanted, which sometimes hinders the next cutting

Embodiment 1
[0040] figure 1 It is a perspective view which shows the tape cutting blade 1 which concerns on 1st Embodiment of this invention.
[0041] Such as figure 2 As shown, the tape cutting blade 1 is mounted on a tape holder for pulling out and cutting the adhesive tape 2 .
[0042] The tape holder is composed of: the reel 6 on which the adhesive tape 2 is installed around, and the cutter part 7 protruding from the position of the reel 6 at a predetermined distance. The adhesive tape 2 unwound from the reel 6 is cut off.
[0043] The tape 2 installed in the tape holder is formed by applying an adhesive on the lower surface of a thin sheet made of film materials such as cellophane, aluminum foil, paper, polyvinyl chloride, OPP, and acetate, and winding it in a roll. of.
[0044] When cutting the adhesive tape 2 , the adhesive tape 2 attached to the reel 6 is pulled out to a desired length, and cut by the cutting blade 1 of this embodiment attached to the tip of the cutter porti...
Embodiment 2
[0106] Next, a tape cutting blade 1' according to a second embodiment of the present invention will be described.
[0107] Figure 12 It is a perspective view which shows the tape cutter blade 1 which concerns on embodiment of this invention.
[0108] Such as Figure 13 As shown, the tape cutting blade 1' is mounted on a tape holder for pulling out and cutting the adhesive tape 2.
[0109] Since the tape holder is the same as that of the first embodiment, description thereof will be omitted by using the same reference numerals.
[0110] The cutting blade 1' of the present embodiment is a cutting blade particularly suitable for an easily torn adhesive tape such as cellophane, and is arranged on the upper end of the cutter portion 7 of the tape holder with the cutting edge facing laterally.
[0111] Below, refer to Figure 12 The configuration of the tape cutting blade 1' of this embodiment will be described in detail.
[0112] The tape cutting blade 1' of this embodiment i...

Abstract
A tape cutting blade capable of rectilinearly cutting a tape in the lateral direction thereof and highly safe. A tape cutting blade having blade units (10) each composed of corners (11) provided at an end of a steel plate (3) having a plate surface extending along a tape (2) and causing the tape to engage with the end to incise the tape, an edge (13) for leading the incision in the direction in which the incision is cut, and recesses (17) connected to ends of the edge (13). The edges of the blade units are arranged along a straight line. A cutting line is formed on the tape by the edges with the tape incised by a corner of a unit blade at a cutting start section, so that a rectilinear cut line is maintained.
Description
[0001] This application is a divisional application for an application whose filing date is June 1, 2008, application number is 200980114834.2, and the title of the invention is "cutting blade for adhesive tape and method for manufacturing the cutting blade for adhesive tape". technical field [0002] The present invention relates to an adhesive tape cutting blade for cutting a roll-shaped adhesive tape into a desired length, and more particularly, to a tape cutting blade capable of cutting linearly and having high safety, and a manufacturing method thereof. Background technique [0003] In tape holders for pulling out and cutting adhesive tapes, food wrapping films, etc., which are wound in rolls, such as Figure 16 The tape holder for the serrated cutting edge 1 (so-called serrated edge) is shown. [0004] In such a sawtooth cutting blade 1, after the tape 2 is pulled out to a desired length, the tape 2' is stretched downward in a state where the head end of the sawtooth is...
