Definitions

  • This invention relates to a system for controlling the operation of textile apparatus and more particularly to a control system for sequentially timing the operation of a textile spinning frame such as a frame provided with la Himalaya slubbing mechanism or attachment which is employed for injecting successive portions of enlarged diameter commonly known as slubs or flakes into yarn as it is processed by the spinning frame.
  • a slubbing attachment with which this invention is particularly adaptable may be of the type manufactured by the Whitin Machine Works of Whitinsville, Massachusetts, and disclosed-in Patent No. 2,069,446, issued February 2, 1937. ln the spinning of yarn, it is often desirable to produce what is known as novelty yarn containing thickened portions or slubs of a predetermined diameter successively spaced along the length of the yarn.
  • slubs give a thick and thin yarn which is useful in producing a fabric having a novel or fancy finish as a result of the prominent nature of the slubsin the fabric surface.
  • the slubs yarn in a random manner so that effect of an unpredictable nature is obtained in the fabric woven from the yarn.
  • randomly occurring slubs produce a commercially attractive novelty fabric, it is often desirable that the yarn, and consequently the fabric, be provided with slubs which occur in a predetermined arrangement or pattern and thus give a fabric Woven from such yarn a surface effect which can be artistically designed and which may be produced uniformly throughout an indefinite length of such fabric.
  • the slubs are injected into the yarn by controlling the draft of the roving processed in the spinning frame.
  • the speed of the back roll is momentarily increased to decrease the draft and produce a thickened portion or slub in the yarn.
  • Many systems have been proposed for timing or controlling such back roll speed changes to produce slubbed yarn, all of which are generally limited in some respect. For instance, many control systems are extremely complicated, require considerable skill to operate, are expensive to manufacture, and are readily subject to breakdown. Furthermore, many of these systems permit only a limited selection of slub pattern due to their limited range of operation, and in many cases, considerable modification or adjustment must be made in the control system for each slub pattern desired.
  • a primary object of this invention is to provide a new and novel control system for textile apparatus.
  • a further object of this invention is to provide a new and novel control system for automatically producing a sequence of control signals of a predetermined duration, the intervals between each of which may be quickly and easily selected throughout a wide range.
  • a still further object of this invention is to provide a control system for automatically timing the slubbing operation in yarn spinning apparatus and which permits .slubs to be injected into yarn processed by the apparatus in a predetermined pattern.
  • This invention further contemplates the provision of a new and novel control system for a Himalaya slubbing attachment in which the draft of the yarn processed in the spinning apparatus is controlled automatically in accordance with one of an indefinite number of patterns so as to produce repeatedly a sequence of slubs throughout the yarn of a predetermined length and spacing'.
  • Still another object of this invention is to provide a new and novel control system for producing control signals in a predetermined repetitive pattern which is simple and inexpensive in construction, readily adaptable to any type of apparatus to be controlled, which may be readily adjusted by a relatively unskilled operator to give any of an unlimited variety of patterns, and which is capable of prolonged use without danger of breakdown.

  • the timing devices are arranged for sequential operation and means are provided for connecting all of these timing devices to electromagnetic means which in turn may be employed to control an operation. Means are also provided for connecting all of these timing devices to a suitable source of power so that the first timing device in the sequence is energized to initiate the sequential operation of the control system.
  • Switch means are provided in each of the timing devices so that as each timing device is actuated, its timing means is activated to begin its predetermined time cycle, at the end of which the next successive timing device is energized accompanied by a simultaneous energization of the electromagnetic means.
  • Relay means also have been provided for automatically repeating the entire sequence in the system which is energized at the end of the time cycle of the last timing device in the sequence.
  • the control system is ernployed to control the yarn drafting operation on a textile spinning frame utilizing a Himalaya slubbing attachment through the electromagnetic means so that the duration and spacing of the signals from the control device to the electromagnetic means may be predetermined by the adjustment of each of the timing devices and slubs of a predetermined length and spacing are formed in the yarn as it is processed in the spinning frame.
