摘要:
A power loom selvage forming device includes at least two thread guide elements for guiding selvage threads. The thread guide elements are guided in longitudinal guides and are connected by transmission elements to a drive shaft driven by a drive motor. The axis of the drive shaft is perpendicular to the direction of motion of the thread guide elements, with the transmission element converting the rotations of the drive motor into longitudinal motions of the thread guide elements containing at least one element mounted on the drive shaft and including articulation points eccentric to the drive shaft and at a mutual angular separation. The drive motor is rotatable by a control into predetermined angular positions at predetermined times.
摘要:
Device for forming a selvedge on a fabric comprising at least one thread guiding element (8-9) for what is called a leno thread (10-11), provided on an arm (16), whereby this thread guiding element (8-9) can be moved by means of a drive mechanism (24), characterised in that the drive mechanism (24) comprises the combination of an oscillating drive element (25); coupling parts (26), and a mechanism (27) with which the movement of one of the above-mentioned coupling parts (26) can be translated in a lateral movement of the above-mentioned thread guide (17-18).
摘要:
A method and apparatus for removing waste selvages (11) formed when weaving fabric on a loom includes a pair of selvage removal rollers (19, 23) fitted with friction coverings and driven against one another to form a gripping nip for engaging and drawing the waste selvage away from the woven fabric, whereby the waste selvage is first fed to the peripheral surface of the first one of the pair of removal rollers (19) over a wrapping angle larger than 150.degree. and preferably larger than 180.degree., before reaching the clamping nip between the rollers (19,23). Alternate embodiments of the invention are described.
摘要:
A pneumatic thread holder for a selvedge device on weaving machines includes a blower nozzle, a support for the weft thread located underneath the nozzle, and an opening for the weft thread in line with the blower nozzle. The opening is enlarged transverse to the blowing direction of the blower nozzle in order to prevent air current reflections or deviations from occurring when the tucking needle passes beneath the opening, thus ensuring that the end of the weft thread remains held in a correct position by the pneumatic holder.
摘要:
A split loom with a stationary loom part and a removable loom part includes selvage-formers mounted in the removable loom part, at least one selvage-former being driven by a shaft entering the loom and also mounted on the removable loom part, the shaft being connectable by a separable clutch to a drive shaft mounted on the stationary loom part.
