In order to cross the strands (32, 37) in the manner characteristic of the braid (e.g. "2 over-2 under") there serve strand guide members (48) which are mounted to reciprocate on guide tracks (49) arranged substantially radially relative to the axis of rotation (1), as well as levers (50) which are arranged substantially in the extensions of the guide tracks (49) and are articulated in the manner of connecting rods at one end to the strand guide members (48) and at the other end to rotating crank levers (52).

Abstract: The yarn feeding device for a yarn-consuming textile machine includes a mechanism for positively feeding yarn to a textile machine according to predetermined yarn consuming speed changes and timings of those changes, this mechanism having a rotary yarn feeding element (1,83) carrying a main yarn reserve (84), a motor (82) for rotating the yarn feeding element (1,83) at a motor rotation speed according to the variable yarn consuming speed and a motor controller (51, 57) for controlling the motor; a yarn reserve device (3,78; 20, 77) for building up or reducing an auxiliary yarn reserve consisting of a portion of yarn extending between the main yarn reserve and the textile machine, when changes in the yarn consuming speed occur that are so rapid that the motor (82) temporarily cannot change the motor rotation speed to deliver yarn from the rotary yarn feeding element at the yarn consuming speed because of motor inertia; a controller for the yarn reserve device (3,78; 20,77) which increases or decreases the auxi

Abstract: In a yarn feeder (2), the yarn feed may be effected by a yarn reserve (11) support spool (2), which is arranged to rotate by means of a motor (60). The yarn is taken up by and unwound from the spool as the latter rotates. Unwinding of the yarn reserve on the spool is not controlled. The size of the yarn reserve is monitored and yarn take-up is controlled accordingly. The unit also includes electrically contactless sensing and control devices (3), which are preferably located immediately adjacent to the rotary spool. The unit (3) is designed to sense the presence and quantity of yarn on the yarn reserve support surface (10) of the spool. The unit also controls the said motor.

Abstract: A strand feeding device can be switched from positive strand feed to intermittent strand feed and vice versa. This is achieved with the aid of a strand guide element which is associated with a lower edge of a storage drum and can be adjusted by an electromagnetic setting member selectively to a first position allowing the intermittent strand feed and a second position producing the positive strand feed.

Abstract: A circular knitting machine has a needle cylinder (7) and a dial (25) which define a comb distance (x). One of these two needle carriers and a respective cam (9, 27) are displaceably supported in a frame of the circular knitting machine. To prevent unwanted changes in the comb distance during temperature fluctuations, a compensating structural component part (30) is provided which is coupled with the displaceable needle carrier, usually the dial and the cam assigned to the latter and constructed and arranged in such a way that the unwanted changes in the comb distance are compensated for automatically by correspondingly dimensioned thermal expansion or upsetting of the compensating structural component part.

Abstract: The invention relates to a device on a knitting machine equipped with slider needles for controlling the laying in of a thread (28) into the open needle hooks (5.2). In order to avoid that the thread is not laid into the hooks correctly or that a thread which has already been laid into the hook, jumps out of the hook (5.2) during the closing movement of the slider parts (6) on account of vibrations or the like, the slider parts (6) of the slider needles are provided with inclined faces (6.5) which project when the hooks (5.2) are closed into the thread spaces (32) formed by these hooks and the needle and slider parts (5,6). In this way the thread portions between the thread guide (29) and the slider needles are pressed deeply into the thread spaces (32) during the closing movement of the slider parts (6), so that the thread sections laid into the following slider needles with hooks still open come securely into the respective thread spaces (32) or are retained therein FIG. 3).

Abstract: For the production of plush knitted goods containing stitches made from main and plush threads, main threads and plush threads are fed to hooks and sinkers, at least the plush threads are pre-formed to plush thread loops by drawing back the knitting tools from a plush thread receiving position into an intermediate position and by, in so doing, drawing and holding taut the plush threads over associated ones of the sinkers, then stitches are formed with the main threads and plush thread loops by drawing back the knitting tools farther into a knocking-over position and by, in doing so, controlling the sinkers in such a way that the pre-formed plush thread loops are held in taut during the stitch formation and that the risk of shortening or undoing of pre-formed plush thread loops during such stitch formation is greatly diminished.

Abstract: The invention relates to a plush or pile knitted fabric comprising a basic knit including a multiplicity of courses and plush yarns or pile fibres which are bound into the basic knit. The basic knit comprises a plain knit formed with at least one basic yarn (1). In accordance with the invention at least one second basic yarn (5) is incorporated into each course in such a way that it is knitted to form stitches (19) at least in selected courses formed with the first basic yarn (1), or forms single-yarn float loops (7) which are disposed between same.

Abstract: A strand or thread feed device, especially for circular knitting machines, is described, having a rotatable storage drum, onto which a predetermined amount of thread is wound and from which the thread is withdrawn in dependence on the thread usage. A brake ring (25) is fitted on the storage drum and consists of a base ring (29) and elastic, bristle-like elements (30) fixed thereon, preferably inclined opposite to the direction of rotation (v) and radially inwardly. In order that the storage drum may be able to accelerate abruptly to its operating speed from rest, without the brake ring (25) being retarded or even not entrained, the peripheral surface of the storage drum is provided with means, e.g. grooves with a sawtooth cross-section, which form abutment surfaces (44) transverse to the longitudinal direction of the elements (30) and with which the bristle-like elements (30) cooperate and ensure form-locking coupling between the brake ring (25) and storage drum in the direction of rotation (v).
