Abstract
Apparatus for forming a bent sheet of foil, comprising a holder for holding a roll of foil; a motor for horizontally feeding the foil from the roll; a bending station for providing the fed foil with an angled portion; a controller for controlling a desired length of foil to be fed by commanding operation of said motor; and a cutting station for cutting said fed foil at said desired length, whereby to form constant length sheets of said foil. The controller is operable to command operation of the motor to sequentially feed the foil a first distance corresponding to a selected longitudinal dimension of the angled portion and then to feed the foil a second distance corresponding to a selected longitudinal dimension of a foil sheet to be formed.
Claims8
A method for forming a bent sheet of foil, comprising the steps of:
- a) selecting desired dimensions of a sheet of metallic foil to be formed;
- b) activating a motor for rotatably driving a roll of said foil, in order to horizontally feed said foil from said roll until an unsupported free end of said foil has a first predetermined longitudinal dimension;
- c) vertically displacing a laterally extending force applier until said force applier sufficiently contacts said free end having said first longitudinal dimension to achieve an angled foil portion of a predetermined angle with respect to said fed foil;
- d) retracting said force applier;
- e) reactivating said motor until said foil is fed for a second longitudinal dimension;
- and
- f) operating a cutting station for cutting said fed foil to form a foil sheet of said second longitudinal dimension.
