摘要:
A device for the electronic adjustment of hosiery tension in circular textile machines, whose particularity consists of the fact that it comprises an actuator which is adapted to move a carriage, which is in turn adapted to perform a translatory motion along an axis which is parallel to a diametrical axis of the circular textile machine, the carriage supporting at least one transducer connected to a hosiery advancement device, the transducer being adapted to detect a contrasting force which is due to the advancement of the hosiery item, the contrasting force being processed in a controller which is adapted to emit a speed signal for the actuator, in order to adjust the movement speed of the carriage in contrast with the contrasting force.
摘要:
An improved fabric take-up apparatus adopted for use on an elevated take-up apparatus with a large capacity includes a frame, a conveying mechanism located in the frame, a take-up mechanism located in the frame, at least one friction mechanism located in the frame between the conveying mechanism and the take-up mechanism, a balancing weight mechanism located on two sides of the frame, a speed changing mechanism located at a lower section of the frame and a stop mechanism located in the frame. The conveying mechanism transports the fabric to the take-up mechanism for rolling. The fabric is rolled until the diameter of the roll increases to contact the friction rod of the friction mechanism, then the friction rod aids the take-up mechanism to roll the fabric. Meanwhile, the friction mechanism is hauled by the balancing weight mechanism so that the friction rod firmly presses the rolling fabric. Thus the friction rod and the fabric may be prevented from being thrown away that might otherwise occur due to the centrifugal force generated by too fast rotation speed during the rolling process.
摘要:
A roller (1) for guiding knitwear produced on a knitting machine, with at least one stub shaft (3) of reduced cross-section projecting to the side of a middle part (2) and at least one first adjusting ring (16) which can be fixed on the stub shaft (3) to form an annular gap is described. The adjusting ring (6) has a first axial end (17) with an outer diameter corresponding to the outer diameter of the middle part (2) and a second axial end (17a) associated with the annular gap (22). In accordance with the invention the adjusting ring (16) is assembled from at least two shells (24, 25) adjoining one another along butt joints (FIG. 5).

A warp knitting machine has across its working breadth in its working area a plurality of knitting tools and an adjacent fabric pull-off arrangement. A pair of gripping breadth holders between the working area and the fabric pull-off are located at both edges of a fabric path. Each of the gripping breadth holders have at least one driven wheel with a plurality of circumferential needles. The wheel is driven through a drive axis that is substantially parallel to the working breadth of the machine. The wheel is mounted to rotate about a wheel axis that is inclined at an inclination angle to the drive axis.
摘要:
A circular knitting machine for producing circular knitwear (15) is described, which is slit at one side, spread out with the aid of V-rolls (17) and then taken down and wound up in the spread out state. In accordance with the invention a guide element (44) if fitted at one end (33) of a fabric spreader (25) and extends up to a junction point (43) of the V-rolls (17). The knitwear (15) is guided by means of the guide element (44) in a controlled manner before running on to the V-rolls (17), such that backing-up and warping during its further transport are avoided.
摘要:
A takedown unit includes a set of takedown rollers arranged around tubular fabric hanging downward from a needle cylinder of a circular knitting machine. The takedown rollers rotate to draw down the hanging tubular fabric, and a floating guide mechanism is within and encircled by the hanging tubular fabric, so that the low-friction guide mechanism interacts with the high-friction takedown rollers to facilitate the drawing down of the fabric. A set of cams extends at least partially around the hanging fabric, and the cams and the takedown rollers are mounted to allow relative rotation therebetween, with the relative rotation being around the hanging fabric. Actuators are positioned for interacting with the cams in response to the relative rotation, so that the cams actuate the actuators which in turn rotate the takedown rollers.
