Strip decoiler

A strip decoiler comprising:

• a. a turntable having a base and adapted to support a coil of strip disposed on its side;
• b. driving means for rotating the turntable;
• c. a vertical mast extending up from the base adjacent one side of the turntable, the mast having at its upper end a horizontal boom extending out over the turntable, the boom having a proximate end attached to the mast and a distant end, a horizontal shaft bearing mounted in the distal end of the boom;
• d. a dancer arm disposed in a vertical plane and having a fixed perpendicular shaft journaled in the shaft bearing and adapted to swing with its lower end moving along a line extending generally radially outward beyond the periphery of the coil, the arm being biased away beyond the periphery of the coil;
• e. a spool shaft;
• f. a spool rotatably mounted on the spool shaft, the spool having a central drum portion and end flanges on either end of the drum portion;
• g. a pair of relatively rotatable radial adjustment elements held in radially adjustable relation by fastener means, one of the elements being mounted on the distal end of the dancer arm, the other being mounted on an end of the spool shaft;
• h. variable electrical resistive means associated with the shaft of the dancer arm and connected with the driving means to relate the speed of the turntable to the angle of the dancer arm relative to the vertical,
• whereby the angle of the spool relative to the dancer arm may be adjusted so that the strip coming from the coil rides flat against the drum portion across the full width of the strip.
