摘要:
A method of controlling the yarns in a yarn selecting mechanism comprising locating yarns separately in a set of carrier tubes, guiding the outlet ends of said tubes into close relationship, selecting a predetermined number of tubes for presentation to gripper means and a griffe frame and causing a griffe bar of said frame to give the selected tubes linear movement into a forward position where the gripper means can grip the ends of yarn projecting from the tubes.
摘要:
A gripper type Axminster carpet loom in which the grippers are so shaped in substantially U-form as to lie always on one and the same side of the path of the weft insertion needle, whereby the weft insertion needle and the grippers can utilize the full loom cycle to perform their respective functions without having to wait for each other to clear the warps.
摘要:
A tuft carrier loading apparatus (10) for loading individual tufts (17) into tuft retention sites (9a) spaced along an elongate tuft carrier (9). The apparatus (10) includes a guide for guiding longitudinal movement of the tuft carrier along a path of travel and a plurality of individually and selectively operable tuft feeders (50) spaced along the path of travel, each tuft feeder (50) being operable when selected to feed an individual tuft to a tuft retention site (9a) of the tuft carrier (9). A driver (70) is drivingly connected to the tuft carrier (9) for moving the tuft carrier (9) along the path of travel, the driver (70) being operable to intermittently move the tuft carrier (9) through a series of successive positions whereat predefined tuft retention sites (9a) are moved temporarily into registry with each tuft feeder (50). A controller (60) is provided for controlling selection of the tuft feeders (50), the controller (60) being operable to actuate selected tuft feeders (50) to feed tufts to those tuft retention sites (9a) in registry therewith whilst the carrier (9) is located at each successive position. A detector is associated with each tuft retention site (9a) to detect the presence of a tuft. The driver (70), on detection of an absent tuft in a tuft retention site (9a) following actuation of one or more selected tuft feeders (50) resulting in failure to feed a tuft to the absent tuft retention site (9a), is operable to move the tuft carrier (9) into a position whereat the absent tuft retention site (9a) is moved temporarily back into registry with the or one selected tuft feeder (50) and the controller (60) re-actuates the selected tuft feeder (50) to feed a tuft to the absent tuft retention site (9a).
摘要:
A device is provided for driving one or several pile carriers (2) for the selection of one or several pile yarns (15), comprising at least one drive motor (4) for driving a pile carrier (2), the pile carrier moving under the motor housing (7) of the drive motor and the motor shaft (5) of the drive motor (4) being provided with driving means (6) for directly driving the pile carrier (2), the pile carrier (2) being provided for performing a linear back and forth movement.
摘要:
A tuft forming mechanism including a yarn feed mechanism and a yarn severing means (6, 18), the yarn feed mechanism including a passage (5) along which yarn (2) is guided to said yarn severing means (6, 18) and an intermittently rotatable feed disc (1) which engages the yarn (2) to advance the yarn (2) along the passage (5).
摘要:
Apparatus for weaving a plain or patterned Axminster pile carpet, wall carpet, floor rug, or mat in which the pile is produced by carrying selected tufts of pile yarn from a yarn feed position to the weaving point by a gripper, and in which at least two distinct heights of pile are produced in an infinitely variable pattern within the normal limitations of the loom.
