Abstract
Abstract A coiled material looping apparatus is provided having a loop guide mechanism which guides the material unwound by the uncoiler mechanism into a spiral loop that spirals or deviates perpendicular to the direction of material feed so that the loop is formed at the side of the coiled portion of the material.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
An apparatus for looping coiled material comprising: an uncoiler mechanism for holding a coiled portion of the material and for unwinding the coiled material by rotating the coiled portion of the material about a horizontal axis; and a loop guide mechanism disposed alongside said uncoiler mechanism for guiding the material unwound by the uncoiler mechanism helically from the coiled portion in a direction perpendicular to the direction of feed and forming a spiral loop of one turn, said loop guide mechanism including an adjustment means for adjusting the position of the loop top and said adjustment means having a fixed end and a free end, said fixed end pivotally fixed alongside said uncoiler mechanism, and said free end extending substantially vertically such that said loop guide mechanism engages said loop at an upper portion thereof, said uncoiler and loop guide mechanisms thereby providing a compact apparatus for looping coiled material.
Claim 2
Independent Claim
150 words
An apparatus for looping coiled material comprising: an uncoiler mechanism for holding a coiled portion of the material and for unwinding the coiled material by rotating the coiled portion of the material about a horizontal axis; and a loop guide mechanism disposed alongside said uncoiler mechanism for guiding the material unwound by the uncoiler mechanism helically from the coiled portion in a direction perpendicular to the direction of feed and forming a spiral loop of one turn, said loop guide mechanism including an adjustment means for adjusting the position of the loop top and said adjustment means having a fixed end and a free end, said fixed end pivotally fixed alongside said uncoiler mechanism, and said free end extending substantially vertically such that said loop guide mechanism engages said loop at an upper portion thereof, said uncoiler and loop guide mechanisms thereby providing a compact apparatus for looping coiled material.
Claim 3
Dependent Claim
36 words
The coiled material looping apparatus as defined in claim 1, in which the loop guide mechanism includes a width guide which determines the position of the material in the direction perpendicular to that of material feed.
Claim 4
Dependent Claim
23 words
The coiled material looping apparatus a defined in claim 1, in which the adjustment means includes a cylinder operated by a pressure medium.
Claim 5
Dependent Claim
18 words
The coiled material looping apparatus as defined in claim 1, which further includes an integral intermittent feeding device.
Claim 6
Dependent Claim
21 words
The coiled material looping apparatus as defined in claim 4, in which said integral intermittent feeding device is a leveler feeder.
Claim 7
Dependent Claim
35 words
The coiled material looping apparatus as defined in claim 1, which further includes a means for detecting the size of the loop and a drive means for the uncoiler mechanism controlled by the detecting means.
Claim 8
Dependent Claim
69 words
The coiled material looping apparatus as defined in claim 6, in which the detecting means consists of a rotatably supported bar, a roller attached to the end of the bar and maintained in contact with part of the loop, a spring to urge the roller so as to follow the loop, and a switch means which is operated when a detecting bar pivots through more than a predetermined angle.
Claim 9
Dependent Claim
32 words
The apparatus as defined in claim 1, wherein said loop guide mechanism additionally includes a plurality of rollers contained within a frame pivotally attached to said free end of said adjustment means.
