ABSTRACT:
In the strip feeding apparatus of the invention, the strip material passes between a lower driven roll and an upper idler roll which is mounted on a vertically slidable adjusting plate so as to move in a pivotal manner towards and from the lower driven roll. The idler roll is mounted on the adjusting plate by means of a pivotal bracket, whereby the idler roll and its bracket can be adjusted bodily in a vertical direction to and from the lower driven roll without disturbing the action of the pressure means forcing the idler roll towards the driven roll and without disturbing the action or timing of the actuating cam which periodically produces a lifting of the idler roll against the pressure of the pressure means.
