摘要:
A device for automatic replacement of the cloth beam (1) in a weaving loom, of the type in which the cloth beam (1) is supported and driven by a pair of driving cylinders (2,3) on which it rests, comprises a pair of cradle arms (6) for supporting a standby cloth roller (1R), automatic means for cutting the fabric, means (9,17) for guiding the edge of the cut fabric around said standby cloth roller (1R) and means for causing rotation of said roller (1R), said cradle arms (6) oscillating between a first position in which said standby roller (1R) is located alongside the cloth beam (1) and a second position in which said roller (1R) comes to rest on said driving cylinders (2,3).
摘要:
Device to modify the geometry of the shed in correspondence of the fabric selvedge, in a weaving loom comprising a yarn carrier bar (T), eventually oscillating, to deviate the warp yarns (O) between a warp beam (S) and a set of heald frames (Q). In correspondence of the ends of said yarn carrier bar (T) there are provided deviation rollers - in the form of idle bushes (1) or of idle pins (2) - apt to cooperate with the sole warp yarns forming the fabric selvedge, the axis of said rollers coinciding with or being parallel to the axis of the yarn carrier bar (T), and their lateral surface being tangent to the plane formed by the warp yarns in the weaving zone when the geometry of the shed is symmetrical and the shed is closed.
