    摘要: A pile patterning mechanism for a circular knitting machine comprises: a sinker bed provided with a plurality of radial, horizontal grooves and disposed on the outer circumference of an upper end of a needle cylinder; a plurality of pile sinkers fitted in the radial, horizontal grooves of the sinker bed so as to be slidable and tiltable. A plurality of horizontal pile jacks each having a plurality of butts are fitted in the radial, horizontal grooves of the sinker bed on the radially outer side of the pile sinkers so as to be slidable and tiltable; and a control unit is provided for controlling the pile sinkers and the pile jacks to slide and tilt the pile jacks and the pile sinkers. The control unit includes a plurality of sinker cams, a jack selecting device provided with a plurality of actuators, and jack cams. The horizontal arrangement of the pile jacks ebables the pile jacks to exert a reliable action on the pile sinker. A knitted article has at least a pile stitch portion of an optional pattern formed by the reciprocating turning operation of a needle cylinder. Pile loops can be formed on optional wales by the reciprocating turning operation of the needle cylinder regardless of the needle loop forming operations of the needles.

    摘要: A picker device having an up-picker mechanism (A) and a down-picker mechanism (B) for increasing and decreasing stitches in knitting a heel portion and a toe portion of hosiery. When the knitting of the heel portion or the toe portion is started, a short butt (2a) of a knitting needle in a knitting level comes in contact with a front end portion (17a or 18a) of an up-picker (17 or 18) as a knitting cylinder alternately rotates forward and backward. The up-picker (17 or 18) is thereby rotated horizontally and a rear end portion (17b or 18b) of the up-picker (17 or 18) is guided by an inclined guide slot (20a or 20b), so that the rear end portion (17b or 18b) is lowered and thus thus the front end portion (17a or 18a) of the up-picker (17 or 18) is raised. The knitting needle (2) is thereby raised from above a stitch cam (9a or 9b) to a position above a center cam (8), whereby the knitting needle (2) is moved to a non-knitting level and thus one stitch is decreased. When one stitch is increased, the short butt (2a) of the knitting needle (2) in the non-knitting level presses a front end portion (25a) of a down-picker (25). The down-picker (25) is guided by an inclined cam portion (21a1 or 21a2) and thereby lowered. Thus, the knitting needle is returned to the knitting level. An actuator (29) that is controlled with a signal received from a knitting control unit (35) locks the front end portion (25a) of the down-picker (25) to a predetermined position. Malfunction or the like of the knitting machine caused by rebounding of the pickers (17, 18, and 25) is suppressed by coil springs (19a and 33).
