TAPE PRESSING ROLLER SET APPLYING DIFFERENT WIPE DOWN PRESSURES

摘要

A pair of wipe down rollers are carried on a respective pair of rotatable arms to which arms force can be applied through separate air actuated cylinders so as to provide that down roller which engages in wipe down contact with the trailing vertical edge of a carton being sealed with tape applies a higher magnitude of positive wipe down pressure to such trailing vertical edge, than is applied by the wipe down roller which engages the carton leading vertical edge.
