Vorrichtung zur Separierung von Abfall beim Schneiden von Papierrollen aus einer langen Stange

摘要

An apparatus is provided for the removal of "trims" and other waste from small rolls of toilet paper, all-purpose wipers and other articles, with arrangement for thrust-operated advancement of rows of said small rolls (R). It includes at least a continuous belt element 12, with a suction box 30 able to hold the small rolls (R) in suspension and to move the latter forward, while excluding the "trims" (RF) or other scraps from this action. The continuous belt element 12 has uniformly distributed apertures (22) and, in its lower active travel portion, moves at a speed at least equal to the average feeding speed of the small rolls. It slides beneath the suction box 30 which exerts a pneumatic aspirating and retaining action on the row of advancing small rolls. The continuous belt 12 has portions without apertures which, during its motion which is synchronized with that of the small rolls being pushed forward, corresponds to the space between the end of a row of small rolls formed from a log and the beginning of the row formed from the subsequent log.
