Abstract
An apparatus for switching a strip feed between supply rolls has first and second supports displaceable in a direction independently parallel to each other between an outer reload position and an inner supply position and respective first and second shafts on the supports extending parallel to the direction and adapted to carry respective rolls of strip. The strip is pulled off one of the rolls in the supply position of the respective support and fed continuously or in steps to a user. Respective cutters on each of the supports cut the respective strip, and respective gluers on each of the supports glue a leading end of the respective strip to a trailing end of the strip of the other roll.
