摘要:
A crank driving apparatus (20) includes a first supporting member (22), a second supporting member (24) including an eccentric shaft (24a), and a coupling member (26) rotatably supported by the second supporting member (24) via the eccentric shaft (24a) and coupled to an object that is to be driven. The second supporting member (24) is disposed in such a manner that an attachment position of the second supporting member (24) relative to the first supporting member (22) is adjustable in an eccentric direction which determines an eccentric distance of the axis of the eccentric shaft (24a) from the axis of a driving shaft (34).
摘要:
A drive-amount changing mechanism for a crank driving apparatus (20) includes a first supporting member (22) attached to a driving shaft (34) so as to be unrotatable relative to the driving shaft (34), a second supporting member (24) attached to the first supporting member (22) so as to be unrotatable relative to the first supporting member (22), an eccentric shaft (25a) supported by the second supporting member (24), and a coupling member (26) rotatably supported by the second supporting member (24) via the eccentric shaft (25a) and coupled to an object that is to be driven. The second supporting member (24) is disposed such that an attachment position of the second supporting member (24) relative to the first supporting member (22) is adjustable in an eccentric direction in which an axis of the eccentric shaft (25a) is positioned eccentric to an axis of the driving shaft (34). The attachment position of the second supporting member (24) relative to the first supporting member (22) in the eccentric direction determines an eccentric distance of the axis of the eccentric shaft (25a) from the axis of the driving shaft (34).
摘要:
In the case of a terry loom, provision is made for the cloth (20) to be displaceable relative to a device for beating up weft yarns through to-and-fro motion of backrest and breast beam, wherein only the backrest for the ground warp and the breast beam may be moved to and fro by means of a drive, while the backrest (16) for the pile warp (13) is held so as to be resiliently compliant substantially in the weaving direction.
摘要:
A loom roll supporting device (65, 75, 85, 95, 105, 115, 125, 135), in which two shaft sections (4b) of a roll (4) that guides warp (W) drawn out from a let-off beam (2) are supported at respective ends of a pair of levers (5,45,54) through first bearings (13) fitted to the shaft sections (4b), and in which the pair of levers (5) are supported by respective frames (1) through second bearings (14) and shafts (7,46) that are fitted to the second bearings (14), includes an arm (11, 35, 38, 40) that is provided at at least one end of the roll (4), that connects the at least one end of the roll (4) and the corresponding lever (5) to each other, and that sets the roll (4) in an unrotatable state.
摘要:
The present invention relates to a fabric support for weaving looms, of the type comprising a main body (2) and a lip (1a) for supporting the fabric (T) and apt to co-operate with a template (4) for tensioning the fabric, which is mounted in an adjustable manner on a base element (30) by means of a rotoidal guide (6) which allows adjustment thereof according to a rotational displacement.
摘要:
The present invention concerns an oscillating warp yarn guiding roller for looms, of the type supported at the ends by levers (9) alternately oscillating in opposition to spring means (8), which consists of a pair of aligned short metal shafts (3b) perpendicular to said levers (9) to which they are fixed at their outer end, while their inner facing ends are reciprocally connected through a thin pipe coupling (12), and of a hollow cylinder (3a) of composite material freely rotating around the pair of short metal shafts (3b), through bearings (11) mounted onto said shafts (3b). Preferably, the composite material of the hollow cylinder (3a) is based on carbon fibres.
