48235970, Apr 25, 1989

Filed:

Jun 6, 1988

Appl. No.:

7/202257

Inventors:

Homer S. White - Durham NC

Assignee:

Myrick-White, Inc. - Durham NC

International Classification:

G01L 504

US Classification:

73160

Abstract:

An improved measuring device for measuring the unit weight of sliver as it passes through a trumpet includes a trumpet gauge plate for supporting the trumpet and a pair of weighted elements mounted on each side of the plate. The plate includes upper, lower and central portions wherein the lower portion includes an opening for supporting the trumpet and the central portion has a reduced cross section. A plurality of strain gauges for detecting deflections is mounted on front and rear surfaces of the central portions adjacent the lower portion and the weighted elements. The strain gauges are electrically connected in a modified Wheatstone Bridge configuration. Deflection sensings in strain gauges adjacent the weighted elements cancel out deflection sensings produced by external vibrations to produce an accurate measurement of the sliver weight.

Homer S. White - Durham NC

International Classification:

D01G 104

US Classification:

19 037

Abstract:

An apparatus and method enables a synthetic fiber tow of indeterminate length passed through a break drawframe to be converted to relatively short spinnable staple length fibers in the form of sliver. During passing through the drawframe, a concentrated beam of energy, illustrated as being a laser beam is swept across the tow by a rotating mirror and in the course of doing so, effectively cuts the tow fibers where struck by the laser beam. In one embodiment the laser beam stays on while sweeping across the width of the tow and then repeats that cycle in a succeeding section of tow. In another embodiment, the laser beam is energized and deenergized as it transverses across one section of tow and in the next succeeding section of tow the laser beam is actuated in a different time cycle.

International Classification:

D01G 1540
D01H 532

US Classification:

19105

Abstract:

A method and apparatus for a textile carding machine or drafting machine drawframe having an out-of-round or otherwise imperfect rotating member is based on detecting and analyzing the relative rotative positions of selected of the machines rotating members in relation to the moment to moment weight of the sliver output and developing therefrom a control signal for varying the speed of rotation of a rotative feeding member so as to vary the sliver weight to compensate for such imperfections.

US Classification:

177153

Abstract:

An improved measuring device for measuring the unit weight of sliver as it passes through a trumpet includes a trumpet gauge plate for supporting the trumpet and a vibration compensating element mounted on the plate. A plurality of strain gauges for detecting deflections are mounted on front and rear surfaces of a central portion of the plate adjacent a lower portion and the compensating element. The plate is mounted on support means, illustrated as a pair of spring supports, which allow the trumpet to move in response to an overload to eliminate damage to the plate, particularly its central portion where the strain gauges are mounted and to return to its normal position after the overload is gone. During normal operation, without an overload, deflection sensing produced by external vibrations cancel out to produce an accurate measurement of the sliver weight and during an overload, the trumpet moves to a new position to avoid damage to the plate and then returns, after the overload is gone enabling the measuring operation to continue.

International Classification:

D01H 572

US Classification:

19239

Abstract:

The present invention provides a drafting apparatus and method having a plurality of pairs of rollers which pairs are each driven in the same rotational direction and have silver contact points oriented along a common straight line. Sliver is fed to the primary rollers through a trumpet guide connected to a strain gage to determine the size of incoming silver and adjust the draft ratio accordingly to equalize the output silver weight. A silver presence and position detecting device operative on a reflected signal is provided adjacent the output of silver, which sends a signal through a computer to adjust the speed of the silver take up apparatus.
