Abstract

To provide substantially uniform winding, reels 10, 12 and 14 are driven by a single rotating shaft 16, each at separate speeds by slip-page of the reels on the shaft due to tension of material 18, 20, and 22 being wound on such reels. The material 18, 20, and 22 can be plastic, paper or thin metal sheets being drawn in parallel through, for example, a bath such as an etchant.

Wind Rewind Station

To provide substantially uniform winding, reels 10, 12 and 14 are driven by a single rotating shaft 16, each at separate speeds by slip-page of the reels on the shaft due to tension of material 18, 20, and 22 being wound on such reels. The material 18, 20, and 22 can be plastic, paper or thin metal sheets being drawn in parallel through, for example, a bath such as an etchant.

Before reaching the reels, material 18, 20, and 22 passes between pairs of rollers 24, 26, and 28. One roller of pair 24 is driven by 30. One roller of pair 26 is driven by motor 32 via shaft 34 and one roller of pair 28 is driven by motor 36 via shaft 38 which is concentrically disposed about shaft 34. Shaft 16 is driven by motor and gear box arrangement 40. Shaft 16 has three sections 42, 44, and 46 joined by tongue and groove connections at 48 and 50 which facilitate removal of any one of the reels from the shaft. The diameter of shaft 16 is slightly smaller than the inside diameter of the reels.

Air is forced through supply line 52 containing valve 54 to a plurality of piston arrangements 56 which urge the upper roller of each pair 24, 26, and 28 toward its associated lower roller. Periodically, under the control of a solenoid switch in motor 30, valve 54 is closed causing springs 58 to lift the upper rollers from material 18, 20, and 22 to permit the material to become realigned within the rollers with respect to the reels. Rollers 24, 26, and 28 can be driven at di...
