ABSTRACT:
Apparatus for producing understrips for cigarette packets of the hinge lid type. A web of the reel-wound cardboard material is dragged along an infeed track, intermittently, by rolls which operate in conjunction with counter rollers and make on the web, parallel with its forward motion, two rows of indentations, punctuated with notches. A cutting device is placed transversely to the infeed track. It consists of a reciprocally movable knife and a stationary knife, and operates in a phase relationship with the web feeding, indenting and notching roll and counter rollers, such that all understrips, detached from the continuous web, are identical. The movable knife has means for holding the understrip detached from the continuous web and for thereby presenting the understrip to apparatus for additionally shaping it and transferring it.
