Abstract
Package wrapping machine infeed conveyor and film web control utilize an infeed conveyor position signal compared to film web signal to adjust the film web letoff to the article in feed conveyor to deliver the article and the film web to a film forming location in register. A processor outputs a digital signal to a motor speed controller which will increase or decrease the feed web letoff rate. Input from the infeed conveyor may be processed by the processor to perform forward or reverse correction as necessary to synchronize the infeed conveyor with the film web letoff.
