HIGH SPEED ERECTING MECHANISM FOR SLEEVE TYPE CARTON

摘要

A stack of collapsed sleeve type end loading cartons are disposed in a hopper and the lowermost carton is engaged and fed out of the hopper by a carton pick up device which rotates in one direction. An auxiliary device rotates in the opposite direction from the direction of rotation of the carton pick up device and engages a carton wall so as to move it out of collapsed condition thereby to initiate set up of the carton.
