Package material processing machine

摘要

A package material processing machine comprises a feeding device for feeding a package material along a predetermined feed course and a processing roller having an outer circumferential surface opposite to the feed course. The package material is processed by rotating the processing roller with feeding the package material along the feed course. In order to process the package material at a desirable pitch with feeding the package material continuously, the machine further comprises a setting device for setting a value correlative with a pitch between a plurality of processed portions on the package material, a feed amount detection device for detecting information correlative with a feed amount of the package material, and a rotation control device for controlling a rotation of the processing roller on the basis of the value set through the setting device and the information detected by the feed amount detection device in such a manner that the plurality of the processed portions are arranged in a feed direction of the package material at the pitch corresponding to the value set through the setting device.
