Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 245 words
A pair of carriers for the filling insertion from a supply package positioned outside of the warp shed on a weaving machine, said pair of carriers consisting of an inserting carrier and a withdrawing carrier each being provided with a thread clamping means, characterized in that, the inserting carrier (30) is provided at its head with a warp end separating part (61) extending virtually parallel to the reed (41) of the weaving machine, the upper edge (62) of the warp separating part having the shape of a rising, concave thread guide cam face which terminates in an open thread groove (63) extending downwardly and which is overlapped by a horn (64) running out toward the reed, clamping means (48) and (69) having a clamping point (79) for the filling yarn (29) which is set back and substantially on a level with the terminal portion of thread groove (63), and further in that the withdrawing carrier (54) on its side facing away from the reed is provided with a front wall (94) disposed virtually parallel to the reed, a clamping piece (90) cooperating with a horizontal clamping bottom member (97), said member (97) extending from the front wall (94) toward the reed, a notch (98) for releasing the filling positioned adjacent to the carrier tip (100) and the clamping bottom Member (97), said clamping piece (90) having adjacent the carrier tip a horn (93) and the front wall having a shoulder (96) overlapping the horn (93).
Claim 2
Dependent Claim 245 words
A pair of carriers for the filling insertion from a supply package positioned outside of the warp shed on a weaving machine, said pair of carriers consisting of an inserting carrier and a withdrawing carrier each being provided with a thread clamping means, characterized in that, the inserting carrier (30) is provided at its head with a warp end separating part (61) extending virtually parallel to the reed (41) of the weaving machine, the upper edge (62) of the warp separating part having the shape of a rising, concave thread guide cam face which terminates in an open thread groove (63) extending downwardly and which is overlapped by a horn (64) running out toward the reed, clamping means (48) and (69) having a clamping point (79) for the filling yarn (29) which is set back and substantially on a level with the terminal portion of thread groove (63), and further in that the withdrawing carrier (54) on its side facing away from the reed is provided with a front wall (94) disposed virtually parallel to the reed, a clamping piece (90) cooperating with a horizontal clamping bottom member (97), said member (97) extending from the front wall (94) toward the reed, a notch (98) for releasing the filling positioned adjacent to the carrier tip (100) and the clamping bottom Member (97), said clamping piece (90) having adjacent the carrier tip a horn (93) and the front wall having a shoulder (96) overlapping the horn (93).
Claim 3
Dependent Claim 32 words
A pair of carriers as defined in claim 1, wherein a clamping piece (69) in the inserting carrier (30) extending in the direction of filling insertion is loosely guided at both ends.
Claim 4
Dependent Claim 29 words
A pair of carriers as defined in claim 2, wherein, the clamping piece (69) is depressed by a flat spring (73) via a ball (75) centered in a hole.
Claim 5
Dependent Claim 33 words
A pair of carriers as defined in claim 1, wherein, the front wall (94) of the withdrawing carrier is provided with a spring plate (107) with a longitudinally disposed, angularly shaped nose (108).
Claim 6
Dependent Claim 23 words
A pair of carriers as defined in claim 4, wherein, the horn (93) together with the clamping bottom (97) form a U-shaped profile.
