Problems solved by technology

[0006] However, in the fastener stringer described in Patent Document 1, the bottom of the groove reaches the tape, so although the left-right width of the element appears to be narrow, the divided part of the first part and the second part Independently bonded, therefore, the bonding strength of part 1 relative to part 2 is low, and the elements sometimes come off from the belt
In addition, the above-mentioned Patent Document 1 also discloses an embodiment in which the bottom of the groove does not reach the belt (see FIG. 10 and FIG. 11 of Patent Document 1), but in this case, between the left and right divided parts of the first part The belt cannot be seen, so the left-to-right width of the elements does not appear to be narrow

Abstract

The invention provides a zipper tooth chain belt. The width of chain teeth is reduced, and at the same time, the strength of chain teeth is enhanced. Each chain tooth (30) comprises an upper part (40)that is arranged on the upper surface of a belt (20), and a lower part (50), which is arranged on the lower surface of the belt. The upper part (40) is provided with a first cut part (41) and a second cut part (42) that are cut in the belt length direction and a reinforcement part (43, 44) that connects the first cut part (41) and the second cut part (42); and the belt (20) is exposed between thefirst cut part (41) and the second cut part (42).

Description

technical field [0001] The present invention relates to a fastener stringer for a slide fastener. Background technique [0002] As a conventional zipper stringer, there is known a zipper stringer that includes a pair of tapes and a plurality of elements respectively mounted along opposite side edges of the pair of tapes, and the elements have The first part on the upper surface side and the second part that is positioned at the lower surface side of the belt and has an engaging head are formed with a groove in the center of the left-right direction of the first part, and the first part is divided left and right by the groove (see, for example, Patent Literature 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Specification of Chinese Patent No. 103564993 [0006] However, in the fastener stringer described in Patent Document 1, the bottom of the groove reaches the tape, so although the left-right width of the element appears to be n...
