Abstract:
A method and apparatus are provided for forming a tubular-shaped knitted covering for a paint roller, or the like, having a pile extending from an outer surface of the covering, through use of a dial needle knitting arrangement. A cylinder needle knitting arrangement may be utilized in conjunction with the dial needle knitting arrangement for forming a tubular-shaped knitted covering for a paint roller having a pile formed from a combination of sliver and yarn fibers in successive courses of the tubular-shaped knitted covering.
Abstract:
Ein Nadelbett (1) einer Strickmaschine ist segmentiert ausgebildet. Die Segmente (5, 6) grenzen mit Anlageflächen (10, 8) aneinander. Von zumindest einer der Grenzflächen (10, 8) gehen Kühlkanäle aus, die z.B. in dem Segment (6) ausgebildet sind. Das benachbarte Segment (5) deckt diese Kühlkanäle ab und verschließt sie somit.
Abstract:
A knitting machine for manufacturing plush fabrics includes latch-less cylinder needles (11) in a cylinder (10), latch needles (21) located on a needle dial (20) and a cutting unit (30). The loop (41) formed by a plush thread (40) can be directly knitted in a fabric formed by ground threads (50) to form a longer plush on the fabric surface. By changing the dimension of the needle dial (20), the interval of the peripheral edge of the needle dial (20) and the cylinder needle (11) can be increased so that the plush thread (40) held on the hook (112) of the cylinder needle (11) can be stretched by the latch needle (21) to become a longer loop. Finally, the loop (41) is severed by the cutting unit (30) to form a plush fabric of a longer plush.
Abstract:
An electronic pattern circular knitting machine and method are provided in which a first encoder (43) is operatively associated with the needle cylinder (14) with which it rotates synchronously and generates a pulse signal for each knitting needle and transmits that signal to a central controller (40) for the knitting machine, in which is stored a datum position for the first encoder, for comparison with pre-stored pattern data to calculate the position of each knitting needle. A second encoder (44) is operatively associated with a dial and its cam system (24), the movement of which changes the knitting timing, for generation and transmission of a position signal to the central controller for comparison with a stored corresponding position to the datum position of the first encoder and a determination of whether the knitting timing has been changed and if so, to adjust automatically the needle selection timing.
Abstract:
A single-cylinder circular hosiery-making or knitting machine particularly for manufacturing tubular items closed at one of their axial ends, the machine comprising a needle cylinder (2) and a circular plate (8) which coaxially faces the needle cylinder (2) in an upward region. The circular plate (8) is composed of two halves (13, 16), a first half (13) of the circular plate (8) being pivoted to a first supporting structure (15) about a diametrical axis (14) which is substantially parallel to the diametrical connecting plane of the two halves (13, 16) of the circular plate (8), the first half (13) of the circular plate (8) being provided with radial grooves (50) which accommodate pairs of hooks (51a, 51b) which can be actuated along the corresponding groove so as to engage or release loops or portions of loops of knitting formed by the needles (4) of the needle cylinder (2). Elements (23, 24, 25, 27) are provided for overturning the first half (13) of the circular plate about the diametrical axis (14) to transfer it from a first position, which is co-planar with respect to a second half (16) of the circular plate (8), to a second position, which is overturned below the second half (16) of the circular plate (8), and viceversa. The first half (13) of the circular plate (8) is rotatable, in the second position, rigidly with the needle cylinder (2) about the axis of the needle cylinder with respect to the second half (16) of the circular plate (8).
Abstract:
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.
