ABSTRACT:
A paperboard sheet feeder for feeding paperboard blanks to the feed rolls of processing equipment includes a support table and a pair of roller assemblies mounted on the support table. A drive includes gears connected to the roller assemblies through one-way clutches. A drive belt has ends secured to a slide block. The belt engages the gears. The slide block is mounted on guide bars for reciprocating movement. The drive belt, gears and one-way clutches convert reciprocating movement of the slide block into rotary movement of the roller assemblies. A source of vacuum communicates with the support table to draw a paperboard sheet into contact with the roller assemblies.
