Patent number: 5133198Abstract: The apparatus has particular use in the detection of flaws in articles being knitted on a circular knitting machine and aplies in particular to the manufacturing of footwear. The apparatus comprises a light source, an electro-optical sensor receiving light coming from the light source after the light has been reflected by the knitted fabric, or after it has passed through that knitted fabric. Devices are provided for processing the data produced by the electro-optical sensor. According to the invention, there is provided a linear endoscope fixedly mounted along the rotation axis of the machine, whose viewing cone is matched to a distal lens and is oriented radially towards the knitted fabric. The photosensitive zone of the electro-optical sensor is located at the image plane of a lens located at a proximal end of the endoscope.Type: GrantFiled: September 6, 1990Date of Patent: July 28, 1992Assignee: Institut Textile De FranceInventor: Jean-Marie Bachmann

Patent number: 4799365Abstract: The device for monitoring the knitwear (16') of a flatbed knitting machine for falling-off exhibits several support bodies (18) having in each case a feeling lever (17) which rests against the knitwear (16') and which is coupled to a switching arm (25). The switching arm (25) is constructed as a contactless contactor and is moved during an adjusting movement of the feeling lever (17), which is triggered when knitwear (16') has fallen off, through the contact range of an electric switching device, for example a light barrier or an ultrasonic barrier or through a magnetic field area into an ineffective end position so that a control signal can be triggered only during the adjusting movement of the switching arm (25) between its end positions.Type: GrantFiled: March 9, 1988Date of Patent: January 24, 1989Assignee: H. Stoll GmbH & Co.Inventors: Ernest Goller, Fritz Walker

Patent number: 4710646Abstract: The invention relates to a thread movement sensor comprising an arm with at least one thread guide. The invention solves the problem of sensitivity of the sensor to the vibrations of the machine by making a part of the arm an element of a magnetic circuit of coil, the latter being connected to the control circuit of a knitting machine.Type: GrantFiled: April 3, 1986Date of Patent: December 1, 1987Assignee: Elitex koncern textilniho strojirenstviInventors: Otakar Curda, Jaroslav Maxa, Pavel Uhlir

Patent number: 4702283Abstract: Optical scanning and inspection of loomed fabric on one or more looms is carried out using a travelling optical scanner that scans an inspection area of fabric on a loom faster than the fabric traverses the inspection area, such inspection area provided between the weaving portion of the loom and the fabric take-up roll. The scanner generates signals that can routinely be compared with preset reference standards and which can be used to control the stopping of the loom upon the detection of a weaving defect. Fabric moving through multiple looms can be scanned in sequence by a scanner traversing multiple inspection areas of the looms.Type: GrantFiled: June 25, 1986Date of Patent: October 27, 1987Assignee: N.V. Weefautomaten PicanolInventor: Henri Shaw

Patent number: 4633914Abstract: Apparatus and method to detect high tension in a web material being taken-up and cutting off the take-up device upon such detection to prevent stretching and necking of the fabric being handled. The detection device provides a time delay between detection of the condition of high tension and deactivation of the fabric take-up apparatus.Type: GrantFiled: March 10, 1986Date of Patent: January 6, 1987Assignee: Milliken Research CorporationInventor: William B. Carry
-
Patent number: 4565076Abstract: A single safety device to automatically stop a conventional circular knitting machine in the event of failure of the belt used to drive a pair of fabric advancing rollers of the machine while the fabric is being knit, and/or to stop the machine in the event of failure to secure the so-advanced fabric to the rotary shaft upon which the fabric is normally rolled to sequentially form individual rolls of fabric on the machine.Type: GrantFiled: October 15, 1984Date of Patent: January 21, 1986Assignee: Precision Fukuhara Works, Ltd.Inventor: Koji Tsuchiya

Patent number: 4464913Abstract: A rundown detector system for controlling operation of the cylinder of a circular knitting machine includes a photoelectric circuit, including fiber optic means and a sensor for sensing predetermined extended periods of low reflected light level and emitting signals to a logic circuit. The logic circuit includes a timer and counting mechanism for stopping rotation of the machine cylinder if a predetermined number of signals are emitted to the logic circuit within a predetermined time period. The timer mechanism also prevents stopping of the machine cylinder, upon start-up of the machine, until a predetermined amount of knit fabric absent of defects has moved past the sensor.Type: GrantFiled: January 12, 1983Date of Patent: August 14, 1984Assignee: Consolidated Foods CorporationInventors: Joel C. Rosenquist, Kenneth J. Thompson, Wayne G. Foster

Patent number: 4454730Abstract: A hosiery handling apparatus for separating individual hosiery articles from a continuous tubular hosiery string and thereafter transporting the separated articles to a remote location includes a control circuit for interrupting operation in the event of a malfunction in the separation of the hosiery string. The control circuit preferably includes an advance switch for detecting passage of a separated article to the remote location and a stop action switch connected in series with the advance switch and responsive to movement of the separating assembly. When a separated article fails to be transported to the remote location, the control circuit terminates operation of the machine.Type: GrantFiled: August 17, 1981Date of Patent: June 19, 1984Assignee: Marvel Specialty CompanyInventors: Clifton Gregory, Lester W. Campbell

Patent number: 4361171Abstract: A weaving detector for detecting weaving defects generated on the surface of a ground fabric of a carpet or rug moving in a first direction is disclosed. The weaving detector moves in the direction of the width of the cloth and includes one or more detecting sensors spaced in the direction of the movement of the cloth. A guide sled is connected to the sensors and has upwardly curved ends so as to prevent the catching of a defect by the sled. The sensors only provide a defect signal when both sensors simultaneously detect a defect. The sensors are supported by upper and lower supports having vibration absorbing springs therebetween so that the electrical controls are not damaged by the vibrations.Type: GrantFiled: April 21, 1980Date of Patent: November 30, 1982Inventor: Tsutomu Fukuda

Patent number: 3999405Abstract: Rotating baffle supported from below substantially closes opening at knitting level of tubular fabric produced by circular pile fabric knitting machine, and deflects air jet carrying stray fiber up toward exhaust intake above machine. Secondary rotating baffle at lower level further reduces movement of air with entrained fiber into tubular fabric, and carries stop motion ring. Rotation of the ring with the goods minimizes skewing at the tube slitting point.Type: GrantFiled: August 11, 1975Date of Patent: December 28, 1976Assignee: Bunker Ramo CorporationInventors: Norman C. Abler, Ralph A. Koegel
