Did You Know...
...that Thomas Edison's patent application on his phonograph was approved by the Patent Office in just seven weeks? In contrast, it took Gordon Gould, the inventor of the laser, 30 years to obtain his patent -- finally awarded in 1988!

| Number | Title | Issue Date |
| 6307340 | Method for starting a power loom A main drive shaft of a power loom reaches the rated operating rpm of the loom by the time of the first beat-up of the reed, thus avoiding start-up faults in the fabric. A flywheel mass is accelerated to a start-up rpm that is higher than the rated operat... | 10/23/2001 |
| 5947164 | Cloth beam arrangement for tubular felts loom A cloth beam arrangement for tubular felts or cloths in a weaving machine brings about feed in the weaving machine of the overfelt and the underfelt. The arrangement comprises an upper first beam, an intermediate second beam and a lower third beam. The un... | 09/07/1999 |
| 5586581 | Cloth roll driving apparatus for driving the cloth roll at two different speeds A cloth roll driving apparatus is provided adjacent to the main shaft of a weaving machine. The apparatus comprises a drive source driven in synchronism with the main shaft of the weaving machine, a slave shaft coupled to a cloth roll and a one-way clutch... | 12/24/1996 |
| 5293906 | Circular loom for and method of weaving ribbon-shaped weft A circular loom comprises weft ribbon shuttle assemblies and a control system for detecting the position of one of the shuttle assemblies at spaced points about the periphery of the loom, and then presetting warp ribbon-setting air cylinders in advance of... | 03/15/1994 |
| 5069257 | Method of regulating the speed of warp threads as a function of weave pattern and warp tension The warp beam and/or cloth beam of a loom is driven by a programmable stepping motor. The speed of the motor is regulated, preferably in such a way that the tension of the warp threads remains constant. Improved tension control is obtained by further prog... | 12/03/1991 |
| 4942908 | Warp transfer control system of loom for filling density change A warp transfer control system for a loom, includes a first actuator for varying a warp let-off speed, a second actuator for varying a fabric take-up speed to change a filling density, and a control unit which has a take-up control section for controlling... | 07/24/1990 |
| 4865082 | Pacing motion for a textile machine The pacing motion which is adapted to be stepped on in respect of individual wefts has a sliding wedge with a return spring. The wedge is displaceable on an output shaft into a groove of an input shaft in both directions of rotation. The motion also inclu... | 09/12/1989 |
| 4817677 | Method for controlling the warp let-off and cloth take-up on weaving machines Method for controlling the warp let-off on weaving machines, with the characteristic that the method consists of: detecting the variation with time of at least one of the parameters which are a function of the warp tension and speed of motion of the warp ... | 04/04/1989 |
| 4712588 | Pick spacing controlling device and method A pick spacing controlling device of the digital system for controlling the pick spacing of a fabric being woven on a loom having a main motor for driving the principal weaving mechanism of the loom, and a take-up motor for driving the take-up roller of t... | 12/15/1987 |
| 4569374 | Device for stopping the cloth takeup regulator in a weaving loom A cam-following roller is brought by a low-power electromagnet into contact with a cam carried by a driving pulley. A second roller which is coaxial with the follower roller exerts a thrust on a disk when the follower roller travels along the profile of t... | 02/11/1986 |
| 4523915 | Reverse weaving mechanisms A coupling device for coupling a loom shaft to the shaft of a weft selecting device in a weaving loom, the device comprising two opposed discs having mutually engaging teeth which automatically respond to reversal in direction of rotation of the loom shaf... | 06/18/1985 |
| 4036266 | Take-up motion for looms This invention relates to an improvement in a cloth take-up motion for looms with gradual or intermittent taking-up of cloth in which a take-up roller is adapted to be driven by drive shaft means and gear system means, and wherein the drive shaft executes... | 07/19/1977 |
| 3973598 | Loom having a cloth take-up system The cloth take-up system positively drives the deflecting roller at a transmission ratio in which the roller has a greater peripheral speed than the cloth take-up roller. A gear-type transmission is used to produce a difference of about 5% in the peripher... | 08/10/1976 |
