Abstract
Abstract A packaging machine adapted to maintain plural webs in registry with a product, including electric eyes disposed in sensing relationship to each web. An infeed conveyor supplies the product. A cam and switch responds to the position of the product relative to the webs one or all of which may be stretchable, and a web brake control system is responsive to signals from the electric eyes and the cam to brake one or all of the webs in order to maintain the webs in registry with one another and the product. The method of maintaining webs of film in registry is also disclosed.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
165 words
A method of maintaining indicia-carrying webs of film in registry comprising the steps of: supplying webs independently from separate rolls; passing each web through its own set of drag pinch rolls under the control of a respective brake; normally applying a nominal working voltage to each brake; sensing the relative positions of the indicia on the webs by individual electrical sensing systems; actuating a timing cam in coordination with the position of a product to be packaged in the webs; detecting relative disposition of the indicia on the webs respectively responsive to signal of the sensing systems; and causing operation of the brake of the drag pinch rolls for the one web on which the indicia are in overrun out of register relation to the other web, comprising supplying an over voltage to the brake associated with said one web responsive to the timing cam and said electrical sensing, whereby a correcting tension is selectively applied by the drag pinch rolls to said one web.
