20090206191 | DEVICE FOR LAYING DOWN A THIN METAL WIRE ON A SURFACE - A device for laying a thin metal wire taken from a coil of wire stock onto a surface, in particular onto the surface of a sheet, using a presser. The device includes a mechanism exerting mechanical tension in a region of the wire that lies between the rotary coil of wire stock and the presser, and a wire-guiding device provided in the region. The wire-guiding device includes a tensioning device that acts directly on the wire taken off the coil of wire stock. That makes it possible effectively and appreciably to compensate for changes in relative speeds at which the wire and the sheet progress. | 08-20-2009 |
20120267467 | BELT-LIKE MATERIAL-FEEDING APPARATUS AND METHOD OF OPERATING THE SAME - A belt-like material-feeding apparatus for continuously feeding a belt-like material to a treating unit, comprises a splicing unit which splices a second belt-like material to a first belt-like material being fed to the treating unit to thereby switch the belt-like material being fed to the treating unit from the first belt-like material into the second belt-like material, an accumulating unit which is arranged between the splicing unit and the treating unit and is capable of temporarily accumulating the belt-like material, and a control unit which, prior to the splicing operation of the splicing unit, increases the amount of accumulation of the belt-like material to be larger than the amount of accumulation of the belt-like material during the steady operation and, during the splicing operation, releases the belt-like material from the accumulating unit to decrease the amount of accumulation of the belt-like material. | 10-25-2012 |
20130099046 | PRINTING APPARATUS AND REWINDER SYSTEM - A printing apparatus is provided which can perform skew correction without damaging the print medium when rewinding a print medium into a roll. Therefore, when rewinding of the print medium roll is performed, the two pairs of conveying rollers are employed, and the conveying speed of the conveying roller pair near the print medium roll is set so lower than the conveying speed of the other conveying roller pair located apart from the print medium roll. Further, a guide member for the print medium is provided between the two pairs of the conveying rollers. | 04-25-2013 |
20140291435 | DEVICE FOR FEEDING YARN TO A TEXTILE MACHINE - A device for feeding yarn to a textile machine, including a main body defining an entry portion and an exit portion for yarn; a rotatable drum for winding the yarn originating from the entry portion and a motor connected to the drum for rotating the drum; a control member active at least on the motor to regulate its torque and velocity; exit portion being selectively switchable between a first configuration in which it defines a free exit section for the yarn, through which the exiting yarn defines a closed path about a rotation axis of the drum, and a second configuration in which it defines a limited exit section, through which the exiting yarn defines an open path. | 10-02-2014 |

20090101745 | Web tensioning device with improved excursion control - A web tensioning device utilizes a dancer device, either angular or linear, which can be positioned by a controlled servo motor. In a preferred embodiment, the controller for the servo motor receives an input signal based on the acceleration (positive or negative) of the dancer device caused by a web excursion and implements a compensation necessary to oppose the web excursion. The controller may also receive additional input signals indicative of the acceleration of the web itself, resulting from the web excursion. | 04-23-2009 |
20110089284 | CABLE TENSIONING DEVICE - A cable tensioning device includes a sheave bracket assembly comprising a plurality of sheaves; and an outlet cable guide attached to the sheave bracket assembly, wherein when tension applied to a cable engaging the sheave bracket assembly reaches a first threshold level, the sheave bracket assembly is adapted to move from a wound state to an unwound state to decrease a path length of the cable with respect to the outlet cable guide. | 04-21-2011 |
20130068872 | Positive yarn feeder with tension limiter - A motorized yarn-winding drum holds a plurality of loops of yarn wound thereon and is driven to rotate for drawing said yarn from a reel and feeding it to a general downstream machine. A movable guiding member is biased to slideably engage the yarn unwinding from the drum and to deviate its path, by a spring acting in contrast to the tension of the yarn, thereby generating a reserve releasable in response to tension peaks on the yarn. The stroke of the guiding member is limited by a stop defining a position of maximum deviation of the yarn. The spring has one end operatively connected to the guiding member and one opposite end connected to driving elements operable for applying a load to the spring, with the guiding member abutting against said stop. The driving elements are controlled by a control unit which is programmed to adjust the load as a function of a desired feeding tension. | 03-21-2013 |
