摘要： A monitoring system for knitting machines, in particular for such machines for the knitting of hosiery or socks, having a number of yearn guards allocated to each yarn for infeed into the machine, the guards each being operative, in response to a movement or absence of movement of the yarn, respectively, detected thereby, to generate and output signal to stop the machine in the event of yarn or thread breakage or other fault int h e yarn infeed, by the intermediary of preferably electronic control unit connected to the yarn guards. The control unit includes memory and comparison systems and is arranged to gather and memorize, during an introductory, correct and approved working or report cycle of the machine, information representing the yarn infeed phase in the form of the actual pattern of output signals from the yarn guards. The control unit is further arranged thereafter to compare, during subsequent working or report cycles of the machine, the pattern of output signals thus registered and memorized during the introductory, correct and approved working or report cycle with the actual pattern of output signals registered during the current, subsequent working or report cycle in order, in the event of a discrepancy therebetween, to generate a fault signal for stopping the machine.

摘要： A yarn feeding device adapted for positively feeding elastic yarn comprises an electric motor, a speed sensor for the speed of the knitting machine and a control unit connected to the electric motor and to the speed sensor. An optimal dynamic behavior of the yarn feeding device is obtained by making use of a rotatable drive cylinder connected to the electric motor, of a rotatable guide shaft supporting the yarn supply spool, which shaft is slidably arranged such that the yarn supply spool is kept in permanent contact with the drive cylinder, wherein the control unit drives said rotatable drive cylinder with a variable speed depending on the actual speed of the knitting machine and on a yarn demand signal, wherein the range of yarn feeding speeds is limited by predetermined minimum and maximum values.

摘要： The invention relates to a method for feeding yarns of different colors to a conventional knitting machine for producing striped fabrics (circle-striped fabrics). The first step of the method according to the invention consists in selecting and presenting a predetermined length of a yarn of a desired color in accordance with the striped pattern to be produced. The so selected and presented yarn lengths are subsequently joined to form a continuous yarn. In a third step, the continuous yarn formed of said joined yarn lengths is intermittently formed into an intermediate store, from which the yarn is positively fed to the knitting machine at a constant speed in synchronism with the operating speed of the knitting machine. In this fourth step of the method, the continuous yarn is fed to the associated knitting system of the machine. Joining of the individual yarn lengths to form the continuous yarn is carried out in synchronism with the operating cycles of the knitting machine, so that the intermediate yarn store is formed at a rate corresponding to the yarn consumption of the knitting machine for each revolution thereof. This permits the splices between the individual yarn lengths to be positioned with high accuracy at the same location of the needle bed during each revolution of the machine. The invention is also directed towards apparatus for carrying out the method (FIG. 1).

摘要： A pulley with a variable working diameter, including two coaxial disks which are rotatable relative to one another, of which the one has a radial and the other at least one spiral-shaped guide groove. A plurality of support members with a segmentlike form are positioned between the disks and can be clamped with their front sides between the disks in different radial positions so that their radially outer peripheral areas define a polygonal path which is similar to a circle. The support members having projections engaged in the guide grooves of both disks so that relative rotation of the disks moves the support members radially for changing the respective circle diameter. Each support member--viewed in the direction of the axis of rotation of the disks--has the shape of an asymmetrical segment, preferably a circular-ring segment, with a longer and a shorter diagonal. An extension of the longer diagonal is spaced from but passes by on the same side of the axis of rotation of the disks as a perpendicular to a tangent on the spiral-shaped guide groove in the area of the support member.

摘要： A thread storage and delivery device comprises a storage drum journalled by bearings on a driven axle.A retaining sleeve is journalled in eccentric inclined bearings at a stationary support of the device and the storage drum respectively. The sleeve is drivingly engaged by a radial arm extending from and fixed to the axle. The driven radial arm winds on the thread coming from a thread supply cone onto the surface of the storage drum.Rotation of the storage drum is prevented by the inclined, eccentric journalling of the sleeve between the stationary support of the device and the storage drum.The sliding movement between the driven radial arm and the sleeve is minimized by the fact that the axis of the sleeve intersect the center axis of the device at a point which is located approximately in a region delineated by notional planes drawn radially to the center axis through the points of driving contact between the radial arm and the sleeve during a complete revolution of the driven axle.

摘要： A thread-delivery device for textile machines, comprising a drum which can be driven for rotation, onto which drum can be tangentially wound a thread coming from a thread bobbin for forming an intermediate thread storage, and from which for positive delivery the thread can be removed tangentially in the area of a removal edge of the drum through a thread-guiding member which is arranged approximately at the level of the removal edge radially outside of the drum. A thread-control element is provided which is transversely movably supported relative to the withdrawn thread, which thread-control element is maintained by the withdrawn thread in one operating position in the area of the thread path between the drum and the thread-guiding member approximately at the level of the removal edge of the drum when the withdrawn thread is at normal operating tension. The thread-control element moves when the thread tension is reduced due to its weight or spring loading into a position below the plane of the removal edge. The thread-guiding member is displaceable from a first position at the level of the removal edge to a second position below the level of the removal edge, or an additional thread-guiding member is provided at the second position below the level of the removal edge. The thread-control element is lockable in a position spaced from the thread path when the thread-guiding member is in its second position, or when the thread travels through the additional thread-guiding member.

摘要： A jet loom with a weft yarn insertion brake contains a braking element that is movable from a position of rest, on one side of the weft yarn, across the path of the weft yarn to a braking position. An electric motor, which drives the braking element, can be actuated during each insertion process of the loom. The electric motor preferably constitutes a fast response step or d.c. motor, whose direction of displacement can be switched and whose stroke can be individually adjusted for each set position of the braking element during the insertion process. Operation of the electric motor is controlled by an electronic control device. Programming within the control device can be modified between varying insertion processes so as to adapt the timing, stroke and driving direction of the electric motor. The driving force of the electric motor is transferred to the braking element by a constrained, inelastic link connecting the two. The electric motor is controlled so that the driving force exerted on the braking element is always greater in magnitude than the greatest possible reaction force of the deflected weft yarn.
