Abstract
Flat tubing is fed from a continuous supply into an embossing station and then into a cutting station and is briefly stopped periodically for an operation in each station. The embossing station has embossing dies for forming a transverse groove in the tube where a cut is desired and for reducing the tube perimeter dimension adjacent the cut to a required size. At the cutting station grippers engage the tubing on either side of the groove and bend the tubing to separate it at the groove.
