摘要:
A fan (21) located in a lower part of an inner section of the creel stand (2) creates an air flow that extends upwardly through a cylindrical duct (20) to a ceiling plate (16) of the creel stand. The air then passes radially outwardly, and thence downwardly through an outer section (30) of the creel stand to filters (9,19) adjacent the bottom of the stand. One of the filters (19) undergoes rotary movement, and fiber waste is conducted from it to a collection source by a suction device.

An automatic winding and doffing apparatus of a circular knitting machine includes a winding unit (4) that revolves synchronously with the cylinder of the circular knitting machine. The apparatus includes opposed winding apparatus frame arms (16,17). A fabric winding roll (21) has one roll end pivotally mounted on one of the arms. A guide mechanism guides the knitted fabric to the winding roll. The fabric roll is stopped after a predetermined amount of fabric has been wound. A doffing apparatus doffs the fabric from the winding roll after a predetermined amount of fabric has been wound on the fabric roll. In preferred embodiment, the other winding roll end is freely supported by a turning lever (28) pivotally mounted on the frame. Upon pivoting movement of the lever arm, the winding roller may be moved from a home, winding position to an unloading, doffing position in which the other end of the winding roller is removed from the support arm. A lock mechanism operatively connects to the turning lever for locking the turning lever in a position in which the turning lever supports the winding roller in the home, winding position and for unlocking the turning lever to allow the turning lever (28) to pivot and disengage from the winding roller (21).

The amount of vertical movement imparted to knitting needles (20) during stitch loop formation is reduced by supporting special types of sinkers (8) for movement in a radial direction along an inwardly and downwardly inclined path of travel relative to the needles (20). As the knitting needles (20) are raised to the latch clearing level, the sinkers (8) are moved inwardly and downwardly to lower the level of the stitch forming ledge (8a) thereof so that the amount of vertical upward movement of the needles (20) is reduced. As the needles (20) are then lowered to stitch drawing level, the sinkers (8) are simultaneously moved outwardly and upwardly to raise the stitch drawing ledge (8a) so that a portion of the length of the stitch being formed is determined by the amount of downward movement of the needle (20) and the remaining portion of the length of the stitch being formed is determined by the amount of upward movement of the sinkers (8).
摘要:
A method for constructing a double fleece knit fabric using a circular knitting machine is disclosed. Lay-in, tie-in and knit-in yarns (57, 58 and 59) are fed at respective first, second and third yarn feeders (60, 61 and 62) to the needle. The lay-in and tie-in yarns (57, 58) are caught by the outward, oblique and upward recession of the sinker. The knit-in yarn (59) is fed to the needle (2) and when received onto the upper edge (8g) of the second nose (8e) is drawn down onto the upper edge (8f) of the first nose (8d) of the sinker (8) when the needle (2) is lowered. The needle (2) is lowered to a stitch loop forming position while the sinker (8) is receded from the innermost lower position to the outermost upward position so that the knit-in yarn (59) falls onto the stitch forming ledge (8a) and the respective lengths of the tie-in yarn (58) and knit-in yarn (59) in the needle hook are drawn downward with the older tie-in and knit-in loops being cleared from the needle (2) so as to form a new tie-in loop and knit-in loop over the stitch forming ledge (8a).

The amount of vertical movement imparted to the needles (1a) during stitch loop formation is reduced by supporting special types of sinkers (8) for movement in a radial direction and along an inwardly and downwardly inclined path of travel (7a) relative to the needles (1a). As the needles (1a) are raised to the latch clearing level the sinkers (8) are moved inwardly and downwardly to lower the level of the stitch forming ledge (8a) thereof so that the amount of vertical upward movement of the needles (1a) is reduced. As the needles (1a) are then lowered to stitch drawing level, the sinkers (8) are simultaneously moved outwardly and upwardly to raise the stitch drawing ledge (8a) so that a portion of the length of the stitch being formed is determined by the amount of downward movement of the needle (1a) and the remaining portion of the length of the stitch being formed is determined by the amount of upward movement of the sinkers (8).
摘要:
Provided is a knitting method and a knitting mechanism, and a circular knitting machine, in which in jacquard or semi-jacquard knitting using a circular knitting machine, welt stitching is avoided so as to prevent the breakage and overlapping of yarns and filaments. According to the present invention, only needles selected for knitting and needles selected for tucking perform stitching, and needles selected for welting are prevented from performing stitching by a deactivation method, and thus the needles selected for welting do not perform stitching, so that the load on old loops can be suppressed, and breakage and overlapping of yarns and filaments can be prevented
