Apparatus for making absorbent pads
Abstract
Abstract Improvement in apparatus and method for producing disposable absorbent pads, such as diapers, comprising applying pressure-sensitive strips of adhesive tape to the diapers by means of apparatus which includes conveyor belt for advancing diapers, the conveyor belt being narrower than the diapers thus allowing the side edges of the diapers to extend beyond the conveyor belt; reel of adhesive tape ribbon disposed at each side and below the conveyor belt; rotatable drum, provided with suction valves, positioned below the overlapping side edges of the diapers, means for advancing the ribbon against the drum whereby the ribbon is held against the drum by the suction valves, rotatable cutting means for severing the ribbon into strips of adhesive tape while the ribbon is held against the drum, situated at each side and below the conveyor belt; and rotatable pressure roll, disposed directly above the rotatable drum, for affixing the strip of adhesive tape to the overlapping edges of the diapers in cooperation with the rotatable drum.
