摘要： A method is provided for contactless optical detection of yarn at a workstation of a textile machine in which the yarn moves in a sensing slot between a source of radiation and an optical sensor having at least one row of radiation sensitive elements, whereby shading of the individual radiation sensitive elements by yarn moving through the sensing slot is monitored and a state of the yarn is evaluated on a basis of the monitoring. The method monitors and evaluates a position of the yarn in the sensing slot or a time course of the position of the yarn in the sensing slot. A change is detected in the position or in the time course of the position of the yarn in the sensing slot corresponding to a yarn break before an end of the yarn break passes through the sensing slot. When the yarn break is sensed, a stop signal is generated for the workstation.

摘要： A method for depositing a yarn end on a bobbin wound on a tube in a defined manner during winding of yarn on the bobbin at a workstation of a spinning and winding machine includes terminating spinning production of the yarn at the workstation to create a yarn end. The yarn end is then prepared with working devices at the workstation, including rotating the bobbin in a direction opposite to a winding direction during production of the yarn. A yarn reserve is formed, and the yarn end is then deposited in a defined manner on the tube outside of the profile of a standard yarn package.

摘要： A process to test the monitoring function of an electronic sensor at the work station of a textile machine in order to avoid wrong decisions by the control unit of the work station. The sensors are tested during operation. For a brief time span a second sensor of the same type is located at the same time within the operating range of the sensor of the working station so that its function overlaps in time with that of the sensor of the work station. During the time of overlap the logical levels of the two sensors are detected, compared with each other and classified as result of the test.

摘要： In a method of obtaining a thread tension signal a sensor in the form of a piezofoil is attached to a thread guide or to its mounting and delivers a signal which reflects, amongst other things, the oscillations induced in the thread guide by the thread movement. In order to obtain a signal which corresponds to the thread tension either the frequency of an element which winds up the thread and/or harmonics of this frequency is filtered out of the sensor signal and the level of this frequency or the level of these frequencies is measured.

摘要： An apparatus for sensing a parting in any of the strands of sliver fed from a creel to the drafting rolls of a high speed textile draw frame to stop the drawing process in response to a sliver parting. A plurality of sliver guides are mounted on an elongate arm which is compact and readily mounted on the creel. The sliver guides are U-shaped with inturned upper end portions defining a restricted opening at the top portion and a capacitive sensing switch positioned in the bight portion thereof. The sliver guides also include a low coefficient of friction coating to reduce the accumulation of lint. Cylindrical post separators are positioned alongside the path of the slivers to maintain separation and prevent entangling of adjacent slivers. Logic and control electronics are contained within a housing carried by the elongate arm.

摘要： An apparatus for carrying out a block-change in a ring spinning machine, in which a block of roving bobbins which each supply an associated spinning station are changed together when the rovings wound on the bobbins run out. Preferably, more than one block of roving bobbins is provided. The roving bobbins used to form a block are combined in such a manner that all of them have at least substantially the same length of roving wound on them. The end of the roving on at least one of the bobbins of the block is detected before that end passes through the associated drafting unit, and the block-change is triggered at an instant of time when the roving end has not yet passed through the drafting unit.

10.发明授权Method and apparatus for piecing a reserve feed stock with a production feed stock 失效用于生产原料用于接收储备原料的方法和装置

摘要： The method and apparatus for supplying a reserve feed stock to a spinning machine or spinning position thereof, contemplates monitoring the operational state of a production feed stock and upon reaching a predeterminate operational state thereof, such as near depletion or depletion of the production feed stock, or even rupture thereof, bringing a reserve feed stock previously held in readiness into a production position where such reserve feed stock now assumes the role of a production feed stock. Consequently, downtime of the spinning machine or spinning position can be minimized and its operation at least partially automated since there is always available a reserve feed stock to allow for essentially continuous or continual production of a spun yarn or thread. One specific piecing technique uses a movable member for placement of a reserve feed stock into the travel path of a production feed stock such that piecing of these two feed stocks is reliably attained. Here the production feed stock may be separated by a clamping or cutting action or the terminal end thereof may be monitored so that the reserve feed stock can be pieced to a desired terminal end section of the production feed stock without the need for any separation operation.
