Abstract: The combination of a self-adjusting payoff and a compact, portable metal forming device comprising: 1) a frame having entry and exit ends; 2) guide means adjacent the entry end for guiding a sheet of metal to be formed to a hand operated drive assembly supported within the frame that engages the metal sheet and drives it, through the operation of a series of gear linked separately journaled forming roll pairs mounted in the frame, 3) adjacent the exit end an adjustable cam wheel that engages one edge of the metal sheet and forms that edge just prior to the metal sheet reaching the exit end, and 4) forming the exit end, a guillotine cutter including a shaped exit aperture for cutting the formed metal sheet to any selected length.

Abstract: A self-adjusting payoff comprising a frame, and a pivoting spool mounted in the frame. The pivoting spool comprises an axle, at least three pivot assemblies slideably mounted on the axle and an adjustment mechanism for adjusting the location of the pivot assemblies relative to the axle. Each of the pivot assemblies comprises a pair of freely rotating, parallel arms extending radially from the axle toward and rotatably attached to coil supports that, when the pivoting spool is adjusted to its most extended position as described hereinafter, extend parallel to the axle. Operation of the adjustment mechanism causes movement of the extremities of the parallel arms proximate the axle to move inward or outward along the axle thereby adjusting the relative distance between the axle and the supports permitting acceptance of variously sized coils by the payoff.
