The working process of the device for attaching the adhesive film at the crotch of the bra loop in this embodiment is as follows:
the tab 5, which has not yet adhered the adhesive film 6, is placed on the upper surface of the portion of the second conveyor belt 122 beyond the first conveyor belt 112 such that the end of the crotch of the tab 5 is exposed 8mm to the side of the second conveyor belt 122, at which time, along with the conveyance of the first conveyor belt 112 and the second conveyor belt 122, the tab 5 is driven to move in a direction approaching the crotch opening assembly. When the tab 5 reaches the opening portion 31 of the bifurcated opening assembly, the crotch of the tab 5 is gradually opened to form an upper crotch 51 and a lower crotch 52, and is pressed against the surfaces of the first and second side plates 21 and 22 by the flat portion 32. After the adhesive film 6 is connected to the first guide groove 42 and the second guide groove 43 of the adhesive film heating and conducting mechanism 4, the adhesive film 6 starts to be conveyed to the direction close to the hook tab 5 and is heated and melted, and the adhesive film 6 is attached to the upper bifurcation surface 51 and the lower bifurcation surface 52 of the hook tab 5 conveyed to the position opposite to the pinch roller 41 by rotating and extruding the pinch roller 41 at the pinch roller 41 of the adhesive film heating and conducting mechanism 4.
