Abstract
Apparatus is described by means of which sheet metal strip, unwound from a coil construct having a vertical axis of rotation, is fed to a strip processing station at regulated rates. The feed rate control mechanism is particularly adapted to accommodate strip that is twisted prior to exiting the apparatus to enable it to enter the strip processing station in a generally surface-horizontal attitude. The apparatus is arranged to occupy a minimum amount of floor space.
Claims7
Apparatus for feeding strip material from a wound coil to a work processing station comprising:
- (a) a turntable adapted to mount a strip coil for rotation about a vertical axis in the strip unwind direction;
- (b) means for rotatably driving said turntable;
- and
- (c) means operably connected to said driving means for controlling the rotational speed of said turntable including:
- (i) a base disposed on the remote side of said turntable from the strip discharge side of said apparatus;
- (ii) a turntable drive control interposed between said turtable and said base;
- (iii) an upstanding post vertically spaced from said base and adapted for translational movement toward and away from said drive control in response to tension on the strip being fed;
- (iv) a frame assembly connected to said post adapted to be embraced by strip material unwound from said coil as it passes toward the strip discharge side of said apparatus;
- (v) link means pivotally connected at its opposite ends to said base and the lower end of said post respectively;
- and
- (vi) means connecting said link means to said drive control to regulate the same in response to the position of said link means.
