FOLDING DEVICE FOR USE IN A MACHINE FOR PACKAGING PRODUCTS IN A WRAPAROUND CARTON AND THE PACKAGING MACHINE

摘要

The packaging machine has means for conveying the cardboard sheet of the carton and the product to be packed together with it in a certain path, as well as deflection means (10). The bending means (10) is arranged as a means of bending a pair of drive tabs cut out of the cartonboard from the plane of the cartonboard inwardly from the plane of the cartonboard on said defined track and has a disk (36) rotatable about an axis of rotation. The essence of the invention is that it has a pair of bending members (14, 16) carried by the rotatable disc (36), which, in a defined position of rotation of the rotatable disc (36), pivotally contact the foldable drive tabs of the carton; having a disk (34) fixed relative to the rotatable disk (36), having an endless guide path (32) about the axis of rotation of the rotatable disk (36), and actuating means associated with the rotatable disk (36) having a follower member (30) that in the guide track (32) of the fixed disc (34) being guided radially in and out by rotation of the rotatable disc (36); 16) is in a cooperative relationship through a hinge-rotation converter. ŕ
