Abstract
Abstract A rotating device for rotatably transferring yarn skeins or hanks from a first generally stationary support or carrier to a second generally movable support or carrier, the latter being substantially at the same level as the first support or carrier, comprises a vertical structure, carrying two slide guides parallel to the movement of the second support; thereon a carriage having a rotating head is movable and has a rotating frame with two slide bars integral therewith; a rod carrying slider moves forwardly and backwardly on the bars, and carries two skein-holder rods which are parallel to each other and can be moved toward and away from each other. Preferably, the rotational movement is given by a cylinder-piston assembly between the vertical structure and an eccentric location on the rotating frame.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
205 words
A device for transferring yarn hanks from a first support or carrier to a second support or carrier, one of said first and second supports being a moving support, said device comprising: a vertical structure (10) having slide guides (12, 13) integral therewith and extending parallel to the direction of movement of said one support; a carriage (16) movable on said guides; means for moving said carriage; a rotatable head (20) carried by said carriage; means for rotating said head; a frame (30) integral with said rotating head; slide bars (32, 33) carried by said rotatable head; a slider (36) movable on said slide bars; means for moving said slider; spreadable skein-holder rods (40, 41) carried by said slider; and means for moving said rods between a closed position in which the rods are parallel and closely spaced from each other and a spaced apart position; said rods in the closed position being insertable into a yarn hank to be transferred from the first support and being moved to the spaced apart position to thereby transfer the yarn hank to said rods, movement of said slider and said rotatable head moving said rods into a position for transferring the yarn hank to the second support.
Claim 2
Independent Claim
205 words
A device for transferring yarn hanks from a first support or carrier to a second support or carrier, one of said first and second supports being a moving support, said device comprising: a vertical structure (10) having slide guides (12, 13) integral therewith and extending parallel to the direction of movement of said one support; a carriage (16) movable on said guides; means for moving said carriage; a rotatable head (20) carried by said carriage; means for rotating said head; a frame (30) integral with said rotating head; slide bars (32, 33) carried by said rotatable head; a slider (36) movable on said slide bars; means for moving said slider; spreadable skein-holder rods (40, 41) carried by said slider; and means for moving said rods between a closed position in which the rods are parallel and closely spaced from each other and a spaced apart position; said rods in the closed position being insertable into a yarn hank to be transferred from the first support and being moved to the spaced apart position to thereby transfer the yarn hank to said rods, movement of said slider and said rotatable head moving said rods into a position for transferring the yarn hank to the second support.
Claim 3
Dependent Claim
46 words
A device according to claim 1, characterized in that said means for rotating said head comprises a cylinder-piston assembly (50), which at one end (51) is pivoted to said carriage (16) and at the other end (52) is pivoted at an eccentric location of said frame.
Claim 4
Dependent Claim
28 words
A device according to claim 1, characterized in that the movement to said carriage (16) is given through a worm screw assembly (W) by a motorvariator reducer (18).
Claim 5
Dependent Claim
21 words
A device according to claim 1, characterized in that said means for moving said slider (36) comprises a cylinder-piston assembly (48).
Claim 6
Dependent Claim
33 words
A device according to claim 1, characterized in that said rotating head (20) comprises a bell-like element (24) which is rotatably mounted by bearings on a pin (22) secured to said carriage (16).
