Abstract
A single-gripper loom (1) comprising: a receiving gripper (5) that is movable along a first sliding guide (6) through a weaving shed (10) from and to a gripping position (P2) outside the weaving shed (10) or close to a first opening thereof (10b) wherein said receiving gripper (5) receives one or more weft threads (2, 3), a weft selector (8), a weft feeder (12) to transfer the weft threads (2, 3) from the selector (8) to the receiving gripper (5), movable along a second sliding guide (7), between an intercepting position (P1) of the weft threads (2, 3), outside the weaving shed, and the gripping position (P2) wherein the receiving gripper (5) receives the weft threads (2, 3) from the weft feeder (12).
Claims11
A single-gripper loom (1) comprising:
- a receiving gripper (5), which is movable along a first sliding guide (6) through a weaving shed (10) from and to a gripping position (P2) wherein said receiving gripper (5) receives one or more weft threads (2, 3) so as to insert said weft threads into said weaving shed (10) from a first opening (10b) to a second opening of said weaving shed (10), said gripping position (P2) being outside said weaving shed (10) or close to said first opening (10b),
- a weft selector (8), which acts on said weft threads to move each of said weft threads (2, 3) between a raised position spaced from said first guide (6) and a lowered position close to said first guide (6),
- characterized in that it further comprises:
- a weft feeder (12) to transfer said weft threads (2, 3) from said weft selector (8) to said receiving gripper (5), said weft feeder (12) being movable along a second sliding guide (7), between an intercepting position (P1) outside said weaving shed (10), wherein said weft feeder (12) intercepts said weft threads (2, 3) in said lowered position, and said gripping position (P2) wherein said receiving gripper (5) receives said weft threads (2, 3) from said weft feeder (12).
A single-gripper loom (1) according to one of the preceding claims, wherein said first and second guides (6, 7) are aligned with each other and said weft feeder (12) is provided with a cavity (13), which is susceptible to housing at least one portion of said receiving gripper (5) in at least said gripping position (P2), said weft threads (2, 3) being susceptible to crossing said cavity (13) when said weft feeder (12) is between said intercepting (P1) and gripping (P2) positions.
A weft feeder (12) for a single-gripper loom (1), which can be coupled with a sliding guide (7) of said loom (1), said weft feeder (12) comprising:
- a cavity (13) for housing a receiving gripper (5) of said loom (1) within said weft feeder (12),
- a first and a second notch (18, 19), susceptible to receiving one or more weft threads (2, 3) so that said weft threads (2, 3) cross said cavity (13) to be gripped by said receiving gripper (5) when said receiving gripper (5) is housed within said weft feeder (12),
- characterised in that said weft feeder (12) is devoid of any gripping element for holding said weft threads (2, 3).
A weaving method for a single-gripper loom comprising the steps of:
- selecting one or more weft threads (2, 3) by means of a weft selector (8),
- intercepting said weft threads (2, 3) by means of a weft feeder (12),
- translating said weft feeder (12) to a gripping position (P2) of said weft threads (2,3),
- in said gripping position (P2), transferring said weft threads (2,3) from said weft feeder (12) to a receiving gripper (5) of said loom (1),
- inserting said weft threads (2,3) into a weaving shed (10) by means of said receiving gripper (5).
