摘要:
Apparatus for removing and collecting fiber waste from a creel stand (10) having multiple, juxtaposed creel sections including an air suction/blower (30) blowing a first air stream across the top of the creel sections and creating a second air stream flowing across the bottom of the creel sections. An air deflector (40) reciprocating across the top of the creel sections deflects the first air stream downwardly through the creel sections. A bottom plenum (60) beneath the creel sections receives the air stream from the creel sections and confines and directs the second air stream to the suction/blower (30). A second blower (70) blows air through the bottom plenum toward the suction/blower to assist the suction/blower in creating the second air stream. A plurality of baffles (64-66) are included in the bottom plenum (60) to provide laminar air flow therein.
摘要:
A fabric take-up unit (5) is supported beneath the needle cylinder (4a) to rotate synchronously therewith and knitted fabric delivery rolls (11, 12, 13) are supported on the fabric take-up unit (5). The fabric delivery rolls (11, 12, 13) are normally driven in response to rotation of the take-up unit (5). In contrast to this normal drive, the knitted fabric delivery rolls (11, 12, 13) are driven by a planetary gear system including a sun gear (17) supported for rotation on the machine frame, a planet gear (18) meshing with the sun gear (17) and being supported on the take-up unit (5). The planet gear (18) is drivingly connected to the fabric delivery rolls (11, 12, 13). A drive motor (34) is fixed on the machine frame and is drivingly connected to the sun gear (17), and a control unit (50) is provided for controlling the speed of rotation of the drive motor (34) and the sun gear (17) so that the quantity of the knitted fabric taken up by the knitted fabric delivery rolls (11, 12, 13) is selectively varied by the speed of rotation of the drive motor (34) and the sun gear (17).

摘要:
A method of and circular knitting machine (20) for producing a knit fabric having more uniform stitches including yarn feeders (76) feeding a plurality of yarns (Y) to stitch forming instrumentalities, the spacing of which affects stitch length and which is subject to change during operation of the knitting machine, a sensor (86) for sensing the tension in the plurality of yarns which changes with changes in the spacing of the stitch forming instrumentalities, and generating a signal indicative of the average tension in the yarns, a comparator for comparing the sensor signal with a pre-set desired tension, a convertor for converting the comparison result into a drive signal, and an adjuster adjusting the spacing of the stitch forming instrumentalities responsive to the drive signal.
摘要:
A yarn changing apparatus for a multi-feed circular knitting machine includes lever arms (22) connected to yarn feeding fingers (12-15). Vertically movable sliders (26) are operatively connected to the lever arms (22) and are slidable between raised and lowered positions to move the lever arms (22) and yarn feeding fingers (12-15) connected thereto, so as to place the yarn feeding fingers into operative and nonoperative positions. Vertically movable rocking jacks (150) pivotably connect to the sliders (26) with each rocking jack (150) including pivotably movable upper and lower ends. Remotely programmed selection units are operative with the rocking jacks (150) for aiding in pivoting the rocking jacks (150). The remotely programmed selection units include upper and lower electromagnetic block units which are energizable and act upon selectors to engage and pivot the rocking jacks (150). Raising and lowering cams engage the rocking jacks (150) to raise and lower the rocking jacks (150) during pivoting movement thereof so as to raise and lower the sliders (26) and move the lever arms (22) and yarn feeding fingers (12-15) connected thereto between operative and nonoperative positions.
