左右的切割器27如圖9及圖10所示，在左右的固定壓力墊26的下表面，設置成相對於左右的鏈帶T能夠平行地滑動。As shown in FIGS. 9 and 10, the left and right cutters 27 are provided to be slidable in parallel with respect to the left and right chain belts T on the lower surfaces of the right and left fixed pressure pads 26.

而且，在切割器27的下表面形成有凸輪槽27a，所述凸輪槽27a與形成於可動壓力墊24的上表面的凸輪24a接觸。因此，可動壓力墊24向上移動，凸輪24a與凸輪槽27a接觸，藉此利用凸輪24a的斜面按壓凸輪槽27a的斜面，切割器27向寬度方向內側移動，而將拉鏈鏈齒E的連結部Ed切斷。因此，切割器27的凸輪槽27a與可動壓力墊24的凸輪24a構成使切割器27移動的凸輪機構。而且，切割器27與固定壓力墊26之間，設置著未圖示的彈簧，所述未圖示的彈簧在可動壓力墊24向下移動時，使切割器27回到寬度方向外側的初始位置。另外，亦可在切割器27的下表面形成凸輪，在可動壓力墊24的上表面形成凸輪槽。Further, a cam groove 27a is formed on the lower surface of the cutter 27, and the cam groove 27a is in contact with the cam 24a formed on the upper surface of the movable pressure pad 24. Therefore, the movable pressure pad 24 moves upward, and the cam 24a comes into contact with the cam groove 27a, whereby the inclined surface of the cam groove 27a is pressed by the inclined surface of the cam 24a, and the cutter 27 is moved inward in the width direction, and the joint portion Ed of the fastener element E is attached. Cut off. Therefore, the cam groove 27a of the cutter 27 and the cam 24a of the movable pressure pad 24 constitute a cam mechanism that moves the cutter 27. Further, a spring (not shown) is provided between the cutter 27 and the fixed pressure pad 26, and the spring (not shown) returns the cutter 27 to the initial position on the outer side in the width direction when the movable pressure pad 24 moves downward. . Further, a cam may be formed on the lower surface of the cutter 27, and a cam groove may be formed on the upper surface of the movable pressure pad 24.

而且，在切割器27的下表面形成有凹部27b，所述凹部27b收容形成於可動壓力墊24的上表面的凸部24b。該凹部27b形成於切割器27向寬度方向內側移動時凸部24b進入的位置。因此，可動壓力墊24向上移動，凸部24b進入至凹部27b，藉此配置於切割器27與可動壓力墊24之間的鏈帶T夾入在凸部24b與凹部27b之間，鏈帶T被朝向寬度方向外側拉伸。藉此，去除鏈帶T的鬆弛，拉鏈鏈齒E的位置及姿勢穩定，因而能夠利用切割器27正確地進行拉鏈鏈齒E的連結部Ed的切斷。 Further, a concave portion 27b is formed on the lower surface of the cutter 27, and the concave portion 27b accommodates the convex portion 24b formed on the upper surface of the movable pressure pad 24. This concave portion 27b is formed at a position where the convex portion 24b enters when the cutter 27 moves inward in the width direction. Therefore, the movable pressure pad 24 moves upward, and the convex portion 24b enters into the concave portion 27b, whereby the fastener tape T disposed between the cutter 27 and the movable pressure pad 24 is sandwiched between the convex portion 24b and the concave portion 27b, and the chain tape T It is stretched outward in the width direction. Thereby, the slack of the fastener tape T is removed, and the position and posture of the fastener element E are stabilized, so that the cutter 27 can accurately cut the connection portion Ed of the fastener element E.

而且，如圖8所示，在模具23的上表面形成有向下傾斜的錐形面23a，在切割器27的前端部的下表面，形成有與錐形面23a同樣傾斜的錐形面27c。藉此，配置於模具23與切割器27之間的鏈帶T以沿著錐形面23a、錐形面27c向斜下方延伸的方式配置。因此，鏈帶T配置於與切割器27的前端隔開的位置，因而可確實地防止切割器27引起的鏈帶T的損傷。 Further, as shown in Fig. 8, a tapered surface 23a which is inclined downward is formed on the upper surface of the mold 23, and a tapered surface 27c which is inclined similarly to the tapered surface 23a is formed on the lower surface of the front end portion of the cutter 27. . Thereby, the chain tape T disposed between the mold 23 and the cutter 27 is disposed to extend obliquely downward along the tapered surface 23a and the tapered surface 27c. Therefore, the chain tape T is disposed at a position spaced apart from the front end of the cutter 27, so that damage of the chain tape T caused by the cutter 27 can be surely prevented.

而且，根據本實施形態的間隙形成裝置20，藉由左右的可動壓力墊24向上移動，而連續拉鏈鏈條C1的左右的鏈帶T夾持於左右的可動壓力墊24與左右的切割器27之間，並且左右的切割器27向寬度方向內側移動，將左右的拉鏈鏈齒列EL的拉鏈鏈齒E的連結部Ed切斷，因而不需要準備僅用於使左右的切割器27移動的驅動裝置。因此，可使間隙形成裝置20進一步小型化，且可進一步削減製造成本。Further, according to the gap forming apparatus 20 of the present embodiment, the right and left movable pressure pads 24 are moved upward, and the left and right chain belts T of the continuous fastener chain C1 are sandwiched between the left and right movable pressure pads 24 and the left and right cutters 27 In the meantime, the left and right cutters 27 are moved inward in the width direction, and the connecting portions Ed of the fastener elements E of the left and right fastener element rows EL are cut. Therefore, it is not necessary to prepare a drive for moving only the left and right cutters 27. Device. Therefore, the gap forming device 20 can be further miniaturized, and the manufacturing cost can be further reduced.

而且，根據本實施形態的間隙形成裝置20，左右的切割器27的移動利用凸輪機構來進行，所述凸輪機構包含形成於左右的切割器27的下表面的凸輪槽27a及形成於左右的可動壓力墊24的上表面的凸輪24a，因而可利用簡單的構造使左右的切割器27移動。因此，可使間隙形成裝置20進一步小型化，且可進一步削減製造成本。Further, according to the gap forming apparatus 20 of the present embodiment, the movement of the left and right cutters 27 is performed by a cam mechanism including the cam grooves 27a formed on the lower surfaces of the right and left cutters 27 and the movable portions formed on the left and right sides. The cam 24a of the upper surface of the pressure pad 24 can thus move the left and right cutters 27 with a simple configuration.
