Abstract: A method for feeding a yarn or thread to a processing machine, such as a textile machine, the method includes unwinding the yarn from a bobbin, bringing it into cooperation with a rotary member and then directing it to a sensor member arranged to verify its feed tension to the processing machine, with monitoring of the yarn feed velocity. The measured tension and measured velocity data being fed to a control unit which controls the yarn feed to the machine. The tension is continuously controlled by the unit to maintain it constant then, if this tension condition is verified, the velocity is controlled to render it constant, while at the same time the tension value is continuously monitored to verify whether it remains constant. This constant tension and constant velocity control of the yarn feed to the processing machine being implemented without synchronization with the machine.

Abstract: An elastic thread supply device including a tension controller configured to control the stress acting upon an elastic thread drawn from an elastic thread package, and a drive roll configured to supply the elastic thread dispensed from the tension controller to a processing line. The drive roll operates at a supply velocity slower than a conveyance velocity of a web, and increases or decreases the supply velocity depending on the fluctuation in the conveyance velocity.

Abstract: A storage feed device for a yarn which unwinds from a corresponding bobbin and is fed to a textile machine. The device includes a rotary or fixed drum and an optical sensor member arranged to sense the movement of the yarn towards the textile machine. The optical sensor includes a plurality of emitters and receivers between which a light beam is generated and is interrupted by the yarn during its movement. The optical sensor includes a first fixed part and a second fixed part which includes the emitter and receiver elements, the first part being coaxial with the rotary member, the second being annular and surrounding the first part, the yarn moving between the parts.

Abstract: Device and method for constant tension feeding, threads or yarns fed to textile or winding machine or metallic wire to similar machine, in discontinuously with phase sequences. The thread motion has at least first and second feeding or absorption states following each other in time. A controller, connected to a tension detector and thread accumulator, intervenes on the accumulator based upon tension value from the detector. A compensator, between the accumulator and tension detector, cooperates with thread to compensate variation of feeding or absorption state of the thread upon passage between each first and second feeding or absorption state. The controller intervenes to modify the accumulator's action on thread and maintain tension value detected by the detector at set value. Interaction between thread and compensator keeping constant tension value during the changing phase of the feeding state. The compensator freely moveable under action of thread relative to a resting position.

Abstract: A device for controlling the feed of a yarn to a textile machine operating intermittently on the yarn, there being provided elements to sense the tension of the yarn and elements for measuring and modifying its feed speed, all connected to control and regulator elements for the tension and speed parameters, which continuously measure the values of both parameters during the feed of the yarn to the textile machine so as to act on a rotary member in order to modify the tension of the yarn when necessary. The rotary member is movable in a controlled manner in the two opposing directions of rotation to feed the yarn to the textile machine or to rewind it in order to prevent its accumulation in correspondence with the machine, the tension of the yarn fed or rewound being maintained at constant values.

Abstract: An automatic fast winding machine includes a machine table, a support frame, a feeding tank, a rotary disk, plural guide rollers, a press roller, a saw-teeth cut device and a collect frame. A large roll of packing film is hung on the support frame. Packing film extends from the large roll, guided by the guide rollers pressed tightly by the press roller, and wound around a cylinder that falls down from the guide hole and supported on one of the support rods, and then the rotary disk turns for 90 degrees once to let the packing film cut by the saw-teeth cut device. Then the cylinder wound with packing film becomes a small roll of packing film to fall down along the collect frame and received and collected therein. All the operations are automatically performed by the machine with fast speed, enhancing production.

Abstract: A greatly simplified roll towel dispenser having far fewer parts than conventional dispensers is shown. The dispenser also has a minimal carbon footprint using recycled materials throughout and a sealed battery for primary power. With the simple dispensing mechanism battery life of months is possible as are remote and portable applications.

Abstract: A yarn feeder having one or more yarn feeler levers which rest on the yarn with a force which in the desired position of the lever, i.e. with a correct yarn run, is small. If the lever is pivoted out because the yarn tension is decreased or the yarn has broken, the force with which the lever rests on the yarn increases. This is achieved in the illustrated yarn feeler by a relief device which partially compensates for the weight of the lever and provides a compensating force as a function of the pivot angle. The compensating force preferably decreases with an increase in further pivotal movement of the lever.

Abstract: The invention refers to a positive yarn feeding method and apparatus, which controls and adjusts the speed of feeding to go with the encoder, thus synchronizes feeding and encoding. The device includes a motor connected to an axle, on which a coupling spins the wheel and activates the belt. The motor receives signals from the positive feeding controller to manipulate its speed. Jointed with the main motor, the encoder outputs reference signals combining the production data with computers, therefore, enhances the production efficiency, shortens the intervals of stop for adjustment, and achieves the practical value.
