ABSTRACT:
To apply a reinforcing element (9) only at the position of an index tab (7) on stock material, in which the position of the index tab, for example alphabetically, shifts from stock material to stock material, the stock material (2) is passed through a groove (27, 27a . . . 27f) extending axially along a cylinder or drum (22), the reinforcements being derived upon cutting a ribbon (15) which is folded longitudinally, and inserted into a groove (27e) of the cylinder while the reinforcement at the opposite side of the cylinder is being applied on the stock material, slid into the groove by a transport system. For application, heated tines press, from the top and bottom, against the reinforcement, by passing through circumferential grooves (69) of the drum or cylinder (22). A movable stop system (17) longitudinally positions the stock material (2) for staggered application of the reinforcements.
