Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a creasing face plate tape used when creasing the developed paper of various paper containers.

(Prior Art) Generally, for scoring processing on a paper container expanded paper, a face plate having a scoring groove is adhered on a fixed lower plate of a punching machine, and a punching blade and a streak are formed on a base paper set on the lower plate. A method is adopted in which an elevating and lowering board having a pushing blade is lowered to punch out the spread paper and, at the same time, to make a creasing at a predetermined position between the creasing groove and the creasing pushing blade. As a scoring face plate used in such a scoring method, conventionally, a scoring blade attachment groove on the upper surface,
Face plate tape consisting of a synthetic resin band-shaped holder having a pair of left and right locking claws on the bottom surface, and a groove tape held by the locking claws of the holder and having a creasing groove on the top surface and an adhesive on the bottom surface, respectively Was developed by first attaching the band-shaped holder that holds the groove tape by attaching the groove for attaching the groove to the groove on the upper plate, then lowering the upper plate to put the groove tape on the lower plate. The groove tape was detached from the holder by adhering and then raising the upper plate to leave it on the lower plate, and only the holder was raised together with the muscle pushing blade.

(Problems to be solved by the invention) However, with this conventional face plate tape, the work of engaging and holding the groove tape in the pair of locking claws of the band-shaped holder at the preparation stage is troublesome and time-consuming, and moreover Since it is difficult for the groove tape to separate from the pair of locking claws when rising, the holder sometimes separates from the muscle pushing blade and remains on the lower plate together with the groove tape, or the groove tape peels off from the lower plate surface. .

The purpose of this plan is to eliminate the conventional drawbacks.

(Means for Solving the Problems) In order to solve the above problems, the face plate tape of the present invention is an elastic material in which a ridge presser groove is provided on the upper surface and a pair of left and right adhesive holding pieces are provided on the lower surface over the entire length in the longitudinal direction. And a groove tape which is held between a pair of adhesive holding pieces of the holder and has a groove for scoring on the upper surface and an adhesive and a separator on the lower surface over the entire length in the longitudinal direction. The tape has a holding adhesive on both left and right ends thereof, a pair of adhesive holding pieces of the holder hang down substantially parallel to each other, and the lower end portion thereof is formed so as to project slightly downward from the groove tape lower surface, The structure is such that the left and right ends of the groove tape are held between both the adhesive holding pieces via a holding adhesive.

(Operation) Therefore, in use, when the muscle pushing blade is inserted into the groove for pushing the muscle pushing blade of the above-mentioned band-shaped holder, the separator of the groove tape is peeled off, and blank driving is performed, the lower surface of the groove tape interposes the adhesive. Since the lower ends of both holding pieces of the holder project slightly downward from the lower surface of the groove tape while adhering to the lower plate, the lower ends thereof open slightly outward and separate or easily separate from the adhesive at both ends of the groove tape. When the muscle pushing blade is raised, the groove tape easily separates from the holding piece and remains on the lower plate, and only the holder rises together with the muscle pushing blade, and removes the holder from the muscle pushing blade and pushes the muscle pushing. Once started, the scoring blade is pressed exactly corresponding to the scoring groove of the groove tape. An embodiment of the present invention will be described below with reference to the drawings.

(Embodiment) In FIGS. 1 and 2, formed on the lower surface of an elongated strip-shaped holder (1) made of a hard elastic material of synthetic resin such as vinyl chloride, polyethylene, polypropylene or the like, by the same hard material of synthetic resin as described above. The tape-shaped groove tape (2) is held by adhesion, and one of the band-shaped holders 1 is made of a synthetic resin plate, and has a U-shape that opens upward at the center in the cross section as shown in the second illustration. There is formed a grooved pusher groove (3) having a narrow deep groove and the lowest end of the groove (3) is used as a positioning part (4), and the left and right sides of the groove (3) are Horizontally from the upper end of the wall to the left and right, and then bend downward to connect U-shaped side frames (5) and (5) in a row, and from the lower ends of both side frames (5) and (5) to the left and right lateral directions. The side plates (6) and (6) are extended, and the short adhesive holding pieces (7) and (7) that hang parallel to each other from the extending ends of the side plates (6) and (6) are projected. I have issued it.

The other groove tape (2) is used to make a creasing at the center of the upper surface in a cross section of a thin plate base (8) having a width equal to the inner side surface spacing of the pair of holding pieces (7) and (7) in the holder (1). While forming the groove (9), a pressure sensitive adhesive or a non-drying pressure sensitive adhesive (10) is applied to the lower surface of the base (8), and the separator (1
1) is attached. At this time, in this example, the adhesive (10) was applied in a slightly larger amount, the separator (11) was attached, and the adhesive (10) was slightly protruded from both left and right ends of the base (8), so that the base (8 The holding adhesive (12) (see FIG. 3) is applied to both left and right ends of the (). The groove tape (2) is inserted between the pair of holding pieces (7) and (7) of the holder (1) as shown in the first and second illustrations, and the grooving groove (9) is inserted into the holder (1). ) Is fitted into the positioning portion (4). Insertion is as simple as pushing the grooved tape (2) from the inside. When inserted like this,
Both adhesive holding pieces (7) and (7) adhere to the holding adhesives (12) and (12) at both ends of the groove tape (2) to hold the entire groove tape (2). In that case, the gap between the inner side surfaces of both holding pieces (7) and (7) and the width of the groove tape base (8) are equal, and the holding adhesives (12) and (12) are the bases.
(8) Since it slightly protrudes from the side edge, the above holding piece (7),
(7) is lightly pressure-bonded to the holding adhesives (12) and (12) to sufficiently hold the adhesive. Both holding pieces (7), the lower end (7 ') of (7),
(7 ') projects slightly downward from the lower surface of the groove tape (2).

As another example, a pair of adhesive holding pieces (7) in the above example,
Bend (7) slightly inwardly towards each other, so that both retaining pieces (7),
It is possible to obtain an example in which the pressure-sensitive adhesive for holding (12) and (12) of (7) is strengthened and other structures are substantially the same as the above example.

In use, the face plate tape of this example is attached by attaching the ridge presser blade attachment groove part (3) to the ridge presser blade (P) of the upper board, and then the separator (11) of the groove tape (2). After peeling off, the upper board is lowered onto the lower board to perform blank driving. In that case, first, the lower end portions (7 ') and (7') of the pair of holding pieces (7) and (7) hit the lower plate,
Then, by further descending, the central part of the adhesive (10) surface on the lower surface of the groove tape (2) adheres to the lower plate and both holding pieces
When (7) and (7) are opened slightly outward and separated from the adhesive between the both ends of the groove tape (2), or easily separated from each other, and when the upper board is raised next, the groove tape as shown in FIG. Tape (2) holding piece
(7), easily detached from (7) and remained on the lower plate, and the holder (1)
Only rises with the pusher blade (P). Remaining groove tape (2)
Is a groove (9) for creasing at a position that exactly corresponds to the pushing blade (P).
It will be glued on the lower plate.

Another embodiment of FIG. 4 is that the lower end portions (7a '), (7a') of both adhesive holding pieces (7a), (7a) are inclined outwardly with respect to each other, whereby the muscle pushing as described above is performed. When the lower ends (7a ') and (7a') of the slant are pressed against the lower plate when the blade is attached and lowered, the holding pieces (7a) and (7a) are easily opened outward. Here is an example.

(Effect) According to the creasing face plate tape of the present invention, since the pair of adhesive holding pieces of the band-shaped holder hang down substantially parallel to each other, the preparatory work for inserting the groove tape between both adhesive holding pieces becomes easy. Moreover, since the groove tape is substantially parallel to the above and the lower end thereof is held via the adhesive for holding between the both adhesive holding pieces protruding slightly downward from the lower surface of the groove tape, the face plate tape of the present invention is pushed. The holder can be easily detached from the groove tape when it is attached to the blade and idled on the lower plate to adhere the groove tape to the lower plate surface and then the muscle pushing blade is raised. It is possible to surely leave it at the initial predetermined adhesion position without peeling from the lower plate surface.
