Yarn reel winder compensating for contact roller moulding inaccuracies

A machine for winding a continually running thread (19) has a mounted rotating spindle for winding the thread on a reel (17). A rotating contact roller (1), supported by a carrier (3) bearing (2), lies on the reel surface (18) with a preset force which can be adjusted by a controllable actuator (4). The bearing is made to be elastic and a sensor (5) on the carrier or the contact roller is so arranged that it detects relative movement in the bearing between contact roller and carrier. The actuator is under control of a controller (6) to which the sensor is connected, in such a way that a desired applied force profile for the roller is achieved. Also claimed is a process for regulation of the applied force where: (a) the relative movement between bearing and applied roller is detected; (b) a signal corresp. to this movement is sent to the controller; an actual bearing position derived from the relative movement is compared with a preset value in the controller and; (c) the actuator is adjusted via the controller to follow the desired force profile. Pref. the sensor is a displacement transducer, i.e. the distance between the opening of a nozzle directing an air stream against a reaction plate and the plate and the resulting varying air pressure is taken as a measure of the application force. Alternatively the sensor is a set of strain gauge foils fixed to the contact roller. The actuator is a piston-cylinder unit which is adjusted by the controller via the control valve (7). Alternatively the unit is adjusted via a pair of two-way valves. An alternative sensor is a transducer which detects the pressure in the unit cylinder and this pressure serves as a measure of the applied force. The controller drives the actuator when a preset acceptable deviation between applied force desired and actual values is exceeded so that either a pressure or a pull is exerted on the contact roller carrier. A control circuit comprising the sensor, the controller and the actuator is ...

Method and device for controlling the height of a web in a packaging machine

A packaging machine (10) that uses cylinders to automatically adjust the pressure gradient on a web feed roller system is presented. The cylinders (106,108) are controlled by an air operated or an electrical sensing device that senses the edge of the web (14). When the sensor (104) detects the web (14) rising it will increase the pressure on bottom of the feed rollers (44) and lower the pressure at the top. This action drives the web down. When the web falls below the proper height the reverse happens and the web is driven back up. This system creates a seeking process that is always driving the web to the correct height. The system can also be used on a pivoting feed roller system. The sensor feedback turns an eccentric that changes the pressure gradient, moving the web to the proper height.
