Abstract

Abstract An endless tape transporting device provided with a reel which has a flange radially projecting an extent of 0.5 to 2.0 mm from the lower side peripheral edge of the reel. Radially extending rollers are also provided in conjunction with the reel and flange for supporting the outermost portion of the tape coil while the flange supports the innermost portion of the tape coil and in this manner transport feeding of the tape from the innermost portion of the coil is facilitated while uniform winding of the same upon the outermost portion of the coil is likewise faciliated.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 217 words
(Amended). A device for transporting an endless tape comprising: means for transporting said tape at a speed of more than 3 m/sec; a supporting rod; a reel rotatably mounted upon said rod and having within its peripheral side surface an annular groove V-shaped in crosssection, said reel holding said tape within said peripheral side in the form of a laminated coil so as to permit said tape to be wound upon the outer most portion of said coil and delivered from the inner most portion thereof through said annular groove; supporting means for supporting the lower side portion of said laiminated coil, said supporting means including a flange fixed to said reel and projecting radially from the lower side peripheral edge of said reel for a distance of from 0.5 - 2.0 mm and at least one supporting roll being spaced a distance of less than 2.0 mm from the peripheral edge portion of the flange and having its axis extending in the radial direction of said reel and being in the form of a cylinder of uniform diameter; and said supporting roll being provided with a transmission roll having its periphery eNgaging the lower side surface of the reel so as to rotate said supporting roll at a speed not greater than the tape traveling speed.
Claim 2
Dependent Claim 217 words
