Certain looms have 1×1, 2×1, and 4×1 shuttle boxes, which enables multicoloured weft yarns to be woven easily.
Micro-computer control cam mechanism
The cam control mechanism in the weaving loom enables effective automation, and is also easy to operate and maintain.
The mechanism of these looms
In an automatic pirn change weaving loom, the yarn extending from the cloth to the shuttle is cut near the shuttle, and the runout pirn is removed from the shuttle, thus unthreading the shuttle eye. Then, the new pirn is inserted into the shuttle with the end of the yarn held in a clamp. When the shuttle makes a first stroke with the pirn, the weft yarn is automatically drawn into the shuttle eye. Then, the old and new ends of the yarn are cut off by selvedge cutters located adjacent to the cloth.
A transfer head is preferably provided for extracting the almost runout pirn from the shuttle and inserting the full pirn. This transfer head is adapted to move between two angularly space apart fixed positions, with one positioned for gripping a pirn in the shuttle, and the second positioned to be stationary beneath the transfer head.
The joint comprises of a knotter that is adapted to receive at least a portion of the wire extending from the almost runout pirn to the shuttle eye, where the pirn is moved by the transfer head. It is also designed to receive a portion of the wire extending from a full pirn, when this pirn is moved by the transfer head. The stripper draws off the remaining wire from the runout pirn when the latter has been extracted from the shuttle and placed in the second position.
