A method and a unit for feeding elements of sheet material to a product wrapping line

摘要

Coupons (2) are fed from a supply station (4) to an assembly station (8) forming part of a wrapping line (3), where they are associated each with a relative product (9). The coupons (2) are engaged along one vertical edge (2a) by the lugs (50) of a looped conveyor belt (44), pushed a set distance along a transfer line (7) sliding internally of a guide channel (31), and released by the belt only after entering the assembly station (8), where the single coupon (2) comes to rest interposed between a product (9) and a relative wrapper blank (12). <IMAGE>
