In this paper, the design for the curve of the picking-up cam is given, on the basis of round labeling machine for pasting the label of beer bottle.

According to the picking-up principles of labeling machine,analyses the work-places of round labeling machine,and designs the transition curve of picking-up cam,concludes the steps for designing the transition curve,proposes the three essential factors merited consideration during designing the transition curve.

Self-regulation system for height of label-affixing machine of cigarette boxes;

This paper introduced a new system in view of improving the problems exited in old style label-affixing machine control system which used in production line of some enterprises.

The article explained how to establish the method of hypothesized operating system on high speed sign machine upon VRML hypothesized reality applicaple platform through the research on hypothesized modelling and emulated operation of the high speed sign machine for beer.
