摘要:
A tuft carrier loading apparatus for loading individual tufts into tuft-retention sites spaced along an elongate tuft carrier which is guided for longitudinal movement along a path of travel having a plurality of individually selectively operable tuft forming devices. Each tuft forming device is operable to feed an individual tuft to a tuft-retention site on the carrier. The carrier moves along said path of travel intermittently through a series of successive positions where predefined tuft retention sites are moved temporarily into registry with each tuft forming devices. By controlling selection of the tuft forming devices, tufts are fed to selected sites while the carrier is located at each successive position.
摘要:
A method of making an Axminster carpet having different heights of pile in the same pile forming pick in which yarn carriers selected to supply high pile are given an additional lift to position the yarns drawn therefrom out of the general plane of yarns drawn-off nonselected carriers. Thereafter means, such as a finger mounted on the knife box, is traversed across the loom ahead of the knife to engage the selected yarns and lengthen them.
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 yarn tuft holder (11) for holding yarn tufts received from one or more yarn tuft inserting devices (2) prior to removal by grippers (13) of a carpet manufacturing machine, comprising a resiliently deformable comb portion (17) for receiving and holding yarn tufts and a rigid comb portion (16) disposed adjacent the resiliently deformable comb portion and for guiding grippers configured to remove yarn tufts held by the resiliently deformable comb portion. Also, a loom for making carpet, comprising one or more of the yarn tuft holders, and a method for making carpet using the loom.
摘要:
For positioning pile yarns in variable selection positions in a carpet weaving machine of the gripper Axminster type, in which pile yarns (1-8) of different colors are placed next to each other in a line in pile yarn loaders (10), each pile yarn loader (10) is brought directly from a selection position to a following selection position. The selection movement thereby remains limited to moving over the distance between two successive selection positions.
摘要:
A method for producing Axminster carpets having two different heights of pile in the same pile forming pick on an Axminster gripper loom. The method comprises engagement of selected yarn carriers on a lifting bar when said yarn carriers move for pile yarn draw-off whereafter the selected yarn carriers are raised and pile yarn drawn-off the selected carriers is raised out of the plane defined by pile yarn drawn-off non-selected carriers.
摘要:
The present invention relates to a method for weaving pile fabrics having at least two different pile heights in a same pile row in a weaving machine of the gripper-Axminster type, comprising at least two pile yarn carriers (2, 3) separately driven for the selection according to a pattern to be woven, of one or several pile yarns (4) being presented, in a position (5) selected, to a gripper (1) driven by an oscillating gripper shaft, provided to draw the selected pile yarn (4) off the pile yarn carrier (2, 3) throughout a length desired, by rotating the gripper shaft. The said weaving machine furthermore comprises a cutting device (6) to cut through the pile yarn (4) selected after the selection and after which this pile yarn (4) is inserted into the fabric. The present invention likewise relates to pile fabrics manufactured according to such a method and to a gripper-Axminster weaving machine to apply this method.
摘要:
The invention relates to a method for driving one or several pile carriers (2) for the selection of one or several pile yarns (15), the pile carriers (2) moving between a first and a second extreme position for pile selection, each pile carrier (2) being directly driven through a drive motor (4), and activating the drive motor (4) for driving the pile carrier (2) occurring either according to the half reset principle, the pile carrier (2), each time being moved over an intermediate position, this intermediate position being a position between two extreme positions for pile selection, and the position of the pile carrier (2) being verified in this intermediate position, or occurring without half reset, one half reset movement being carried out in verification of the fact whether all pile carriers (2) are still in the positions verified, after a number of movements of the pile carrier (2) or after a certain time, said half reset movement being a movement of one or several pile carriers towards an intermediate position between two extreme positions for pile selection before moving to a next position for color selection.
