ABSTRACT:
A machine for embossing comprises a pair of co-operating rollers parallel to but spaced from one another, and two pairs of pinch rollers also parallel to and spaced from one another, one pair of pinch rollers being effective to firmly grip a workpiece before it enters the embossing zone. One set of pinch rollers is located at each respective side of the embossing rollers, and a retractor coupling the upper roller of each said set to the machine frame, arranged in one mode to firmly grip the workpiece and in another mode to be clear of the workpiece. This arrangement enables the rolling machine to operate in two directions.
