Abstract
Abstract In a reeling apparatus for moving webs, such as paper webs, irregular tensions on the web due to thickness variation in the same are eliminated by providing an even pressure along the reel between the reel and at least one driven supporting roller supporting the reel and rotating it by circumferential contact. The invention is specifically applicable to the reeling of barrel shaped reels or reels of similar form deviating more or less regularly from the ideal cylindrical shape. It provides sensor means in contact with the reel for sensing the mantle shape thereof, said sensor means operating measurement converter means transmitting signals based upon said mantle shape. These signals are received by a control unit controlling the deflection or bending of the supporting roller, which thus must be of the known type having controllable deflection. The sensor elements may be mounted onto several load roller arranged closely together above the reel and independently vertically movable but loading the reel with an even line pressure. This may be achieved by having said load rollers pneumatically or hydraulically controlled and thus also pneumatically or hydraulically interconnected.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
In a reeling apparatus of the type in which web material is wound into a reel supported by at least one driven roller in rolling contact engagement with the outer mantle of web material on the reel, the improvement which comprises an internally pressurizable roller disposed in rolling contact engagement with said mantle to support said reel; sensor means disposed for contact with the mantle at locations across the width thereof to sense the contour of the mantle and establish signals corresponding to such mantle contour; and control means responsive to said signals and operable to vary the internal pressure of said roller in accordance with said signals to adjust the deflection of the roller according to the sensed mantle contour and thereby correspondingly adjust the contact pressure between the roller and reel mantle to maintain a generally uniform contact pressure over the width of the mantle.
Claim 2
Dependent Claim
