Abstract
Cutting device for face-to-face weaving loom, having a cutting rail (2) on which a cutting carriage (4) moves to and fro and is connected to a rope (6) which forms a closed circuit with the cutting carriage (4) and moves to and fro, being driven by a reciprocating rotary drum (7). One or more parts of the rope are deflected around guide rollers (11, 12), (24, 25), (16, 17, 18), so that together they cause an S-shaped deflection lying both between the main frame (1,1') and a side frame (10, 19) and between the main frames (1, 1') themselves, in the same plane, with a deflection angle of at least 150 degrees.
Claims16
Drive for a cutting device of a face-to-face weaving loom, the cutting device drive comprising a cutting rail on which a cutting carriage moves reciprocally, the drive comprising a rope which is connected to the cutting carriage, which forms a closed circuit with the cutting carriage and which reciprocally moves, the cutting carriage on the rail, the rope being driven by a reciprocating rotary drum, characterized in that a first part of the rope coming directly from the drum is deflected at a certain distance by a first set of plural guide pulleys comprising a first guide pulley of the set in conjunction with a second guide pulley of the set, so that together they cause an S-shaped deflection of the rope lying between a first side frame and a first one of two main frames of the weaving loom.
Cutting device for a weaving loom equipped with a drive, the cutting device comprising a cutting rail on which a cutting carriage reciprocally moves and, the cutting carriage is connected a rope which forms a closed circuit with the cutting carriage and which reciprocally moves the cutting carriage, the rope being driven by a reciprocating rotary drum, characterized in that a first part of the rope coming directly from the drum is deflected at a certain distance by a first set of plural guide pulleys comprising a first guide pulley of the set in conjunction with a second guide pulley of the set, so that together they cause an S-shaped deflection of the rope lying between a first side frame and first one of two main frames of the weaving loom.
Weaving loom equipped with a cutting device, the cutting device comprising a cutting rail on which a cutting carriage reciprocally moves while being connected to a rope which forms a closed circuit with the cutting carriage and which reciprocally moves the cutting carriage, the rope being driven by a reciprocating rotary drum, characterized in that a first part of the rope coming directly from the drum is deflected at a certain distance by a first set of plural guide pulleys comprising a first guide pulley of the set in conjunction with a second guide pulley of the set, so that together they cause an S-shaped deflection of the rope lying between a first side frame and first one of two main frames of the weaving loom.
A face-to-face weaving loom having a frame, a cutting rail connected to the frame, a pile-cutting device mounted on the cutting rail and a drive connected to the cutting device, the cutting device comprising a cutting carriage mounted on the rail for reciprocally moving, the drive comprising a rope which forms a closed circuit connected to the cutting carriage for reciprocally moving the carriage, and a reciprocating rotary drum mounted on the frame and connected to the rope for moving the rope to and fro, characterized in that plural guide pulleys in at least one set mounted on the frame and connected to a part of the rope coming directly from the drum deflect a first portion of the rope by a first guide pulley in the set in conjunction with a second guide pulley in the set and for together causing an S-shaped deflection in the first portion of the rope.
