| 20120104140 | METHOD, MANDREL AND DEVICE FOR THE REMOVAL OF CORELESS ROLLS OF A STRETCH FILM - A method, a mandrel and a device for removing coreless rolls of a plastic film. The mandrel comprises a tubular body having a plurality of radial holes, conformed with a chamber for distributing pressurised air, in which a piston suitable for being magnetically coupled with an external drive member slides. When a roll must be removed, pressurised air is supplied to the fore end of the mandrel, and escapes from all the holes to expand the internal turns of the roll which can be taken off without friction. As the roll advances along the mandrel, the magnetically driven piston progressively reduces the volume of the air chamber preventing at the same time the air to escape from the holes that progressively come to lie on the rear side of the mandrel, with consequent saving of compressed air. | 05-03-2012 |
| 20110017861 | CORE ASSEMBLY FOR WINDING SHEET AND WINDING METHOD - A core assembly for a continuous sheet includes a core of a cylindrical form. A side channel is formed in the core to extend fully in an axial direction thereof. A shaft hub is disposed through the core movably in the axial direction. A changing unit or adjuster displaces the core in response to moving of the shaft hub between first and second positions, and enlarges an outer diameter of the core when the shaft hub is in the second position than when the shaft hub is in the first position. Preferably, the changing unit includes a cam roller, disposed on the shaft hub, for projecting in a radial direction. A cam ramp surface is formed with an inner surface of the core, has a height increasing toward the second position, is pressed by the cam roller. | 01-27-2011 |
| 20110168830 | Center/Surface Rewinder and Winder - A winder for winding a web to produce a rolled product is provided. The winder includes a web transport apparatus that is used for conveying the web. Also included in one exemplary embodiment is a plurality of independent winding modules. The winding modules are independently positioned to independently engage the web as the web is conveyed by the web transport apparatus. The winding modules may be configured to wind the web to form a rolled product by center winding, surface winding, and combinations of center and surface winding. The winding modules are structurally and operationally independent of one another where if one module is disabled, another may still operate to produce the rolled product without shutting down the winder. | 07-14-2011 |
| 20100243789 | SYSTEM AND METHOD FOR PREPARING WINDING MANDRELS FOR FORMING REELS - Disclosed is a system to be combined to one or more rewinding machines ( | 09-30-2010 |
| 20110180650 | ROLLING SYSTEM FOR ROLLING STRIP-SHAPED ROLLING STOCK - The invention relates to a rolling system for rolling strip-shaped rolling stock, comprising at least one first ( | 07-28-2011 |
| 20100327101 | Rolling System for Rolling Strip-Shaped Rolling Stock - A rolling installation for the rolling of in-process stock in the form of strip having a first reel, a second reel, with at least one stand between the reels, and with assigned coil transport trucks. Each reel is designed as a reversing reel, namely as an uncoiling and coiling reel. | 12-30-2010 |
| 242533100 | With particular spool supply hopper | 1 |
| 20090057475 | AUTOMATED SLEEVE FILLING FOR WINDING SHAFTS ON ROLL SLITTING AND WINDING MACHINES - A method for automatic sleeve filling of a winding shaft on roll cutting and winding machines is provided in which, in an exemplified embodiment, in a first step at least two empty winding sleeves are slid onto a free end of a winding shaft so that the winding sleeves are adjacent to one another, in a second step the last winding sleeve slid on by a freely positionable fork piece of a freely programmable draw-off plate along the winding shaft is slid over the winding shaft until the last winding sleeve has reached a predetermined position, in a third step the next-to-last winding sleeve slid on is grasped by tongs freely positionable along the winding shaft and is slid over the winding shaft to the point where in a fourth step the fork piece can dip into the gap produced by the tongs so that the next-to-last winding sleeve is positionable along the winding shaft by the fork piece. | 03-05-2009 |
