Abstract

PURPOSE:To simplify the work of attaching strings onto small pieces and enhance productivity by passing through the strings in channels provided on a frame, placing the strings on two small pieces in parallel, overlapping the small pieces on the same and welding integrally the small pieces upper and lower. CONSTITUTION:Endless ring elastic strings 11 are stretched straight and passed respectively through channels 3 correspondingly both sides of a frame 2, and both ends of strings are pinned with pins 4 in the state of being positioned on two small pieces 8 arranged juxtapositionally to each other, and then thermoplastic sheets 14 disposed with small pieces 13 encircled with similar cutting lines 12 in the positions corresponding to the small pieces 8 are placed on the strings 11, and upper section electric pole bolts 15 are lowered on respective small pieces 13 and the upper and lower small pieces 8 and 13 are welded integrally to clamp strings 11 between said two, and sites other than the small pieces 13 on the thermoplastic section 14 are pulled out and the strings 11 are cut between the two small pieces in parallel. The strings can be placed on the small pieces efficiently by said arrangement.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for manufacturing a fastening set-up tack, and particularly to one in which the string is annular.

(Prior art and problems to be solved) Conventionally, one string was attached to each small piece, which resulted in extremely low productivity.Therefore, the present invention provides a method for attaching strings to small pieces more efficiently. The purpose is to improve productivity by making it easy to install.

(Means for Solving the Problems) In order to achieve the above object, the method for manufacturing an assembled tack in the present invention includes a frame body (2
), and grooves (3) are formed oppositely at predetermined positions on both left and right sides of the frame body (2), and grooves (3) are installed on the outside of both sides.
A board (5) having a protruding pin (4) corresponding to the board (5) is configured,
First, the release mount (6) is placed inside the frame (2) on the lower electrode plate (1) of this substrate (5), and then the small pieces (8) surrounded by the cutout line (7) are placed two at a time. The thermoplastic plastic sheets (9) arranged in parallel at predetermined positions are placed on the above-mentioned release mount (6).
) on the adhesive α1, then remove the parts other than the small piece (8), and then stretch the endless annular elastic string (11) in a straight line to form the corresponding @ ( 3)
The above two parallel pieces (
8) While it is positioned above, attach both ends of it to the above pins (
4), and then placed a small piece (13) surrounded by the tear line (l) in the same position as the above small piece (8). Place the thermoplastic glass sheet α4 on the string (11). Then, lower the upper electrode rod (151) onto each small piece α3 and weld the upper and lower pieces (8) α3- together, sandwiching the string (11) between them. This method is characterized in that a portion of the thermoplastic plastic sheet α other than the small piece αJ is subsequently extracted and the string (111) is cut between the two parallel pieces.

(Example) Examples will be described with reference to the drawings.

First, as shown in Figure 1, a Bakelite rectangular frame (2) is attached to the upper surface of an aluminum lower electrode plate (1), and a plurality of grooves (
3) are provided opposite to each other, and pins (4) are provided protrudingly at positions corresponding to the outer grooves (3) on both sides of the substrate (5). The pins (4) are provided alternately at points near and far from the groove (3) along each side of the frame (2), and are provided at a point close to the groove (3) on one side. The position of the pin (4) on the other side that corresponds to the pin (4) that has been placed is adjusted so that it is provided at a point far from the groove (3). First, a release mount (6) whose upper surface is coated with wax is placed inside the frame (2) on the lower electrode plate (1) of this substrate (5). Next, a small circular piece (
Transparent thermoplastic sheets (9) such as PVC sheets (9), which are arranged two by two in parallel to form seven sets, are arranged in two rows on the left and right with their positions shifted from each other. 6) After polymerization, parts other than the small piece (8) are extracted. Next, an endless annular elastic string aυ made of rubber or the like is stretched in a straight line and the corresponding grooves (3) on both sides of the frame (2) are stretched.
) and placed on a set of two parallel pieces (8), then hold both ends of the pieces with pins (8).
4) is latched. At this time, the small piece (8) is attached to the frame (
2), but one end of the string a1) is located on the pin (4) near the groove (3) on the side of the frame (2), and the other end is on the frame (2). Since it is hung on the pin (4) far from the groove (3) on the other side, the small piece (2) is located approximately in the center of the string (11).

In addition, it is also possible to arrange the same number of small pieces (8) without overlapping the string αB. Next, a thermoplastic plastic sheet (141 is the string (11
) (see Figure 2 above).

Next, the upper electrode rod α9 of the welding machine whose lower end pressure welding part is in the shape of a cross is lowered onto each small piece α■ as shown in FIG. aυ is sandwiched.Then a thermoplastic sheet α
The small pieces (other than 13) in a are extracted.Then, the string Uυ is cut between the two small pieces that are removed from the substrate (5) and arranged in parallel with each other, and a large number of pieces are placed on the release mount (6). An assembled tank will be formed (see Figure 4).For example, when attaching to an envelope or bag, it should of course be peeled off from the release mount (6) and attached to the back of the lower piece (8). It may be attached using adhesive α1 as shown in FIG.

(Operations and Effects) The present invention is based on the above-mentioned case, and the string is passed through the groove provided in the frame, and the string is positioned on two parallel pieces, and then the pieces are stacked on top of the string, and the upper and lower pieces are stacked on top of each other. By welding the small pieces together, the string is sandwiched between them, and finally the string is cut between the two pieces, so attaching the string to the small piece is easy and simple. Since a string can be attached to each piece, it has the effect of greatly improving productivity. By the way, if the structure is configured as described in claim 2, the tack on which the string is latched can also be easily manufactured at the same time.
