Abstract
Abstract Apparatus for transferring a continuous web of sheet material being wound onto a reel to a fresh core employs a rider roll to press the web as it is being wound and a guide roll for the web during transfer. Conveniently the reel and core are on a turnover stand and during transfer, when the reel is moved away from the rider roll, the guide roll is engaged with the web between rider roll and reel to avoid too long an unsupported run. It is also used to assist in wrapping the web around the new core and a web cutter is mounted in close association therewith. The sequence of movements of reel, core, rolls and cutter can be automatically controlled.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
255 words
A method of transferring a continuous running web of sheet material being wound into a reel on to a fresh reel core, the reel and core being mounted and rotated at opposite ends of the pivoted arms of a turnover stand, wherein, before being wound upon the reel, the web is led around an idle rider roll which rides upon the outermost winding of the reel, and wherein the transfer of the running web from a completed reel to a fresh reel core is effected by pivoting said arms to move the reel apart from the rider roll to draw out a length of web between them, the rider roll remaining stationary, introducing a guide roller into the path of this length of web from the side opposite to the reel, moving the rider roll apart from the reel, further pivoting said arms to bring the fresh reel core into the path of the length of web between the guide roller and the rider roll in close proximity to the guide roller, and returning the rider roll to nip the web against the fresh reel core so that the web is caused to envelop the greater part of the periphery of the fresh reel core solely by two elements, namely the rider roll and the guide roller, and actuating a knife and transfer mechanism to cut the web between the fresh reel core and the guide roller and to transfer the leading end of the cut portion to be wound upon the fresh reel core.
Claim 2
Independent Claim
255 words
A method of transferring a continuous running web of sheet material being wound into a reel on to a fresh reel core, the reel and core being mounted and rotated at opposite ends of the pivoted arms of a turnover stand, wherein, before being wound upon the reel, the web is led around an idle rider roll which rides upon the outermost winding of the reel, and wherein the transfer of the running web from a completed reel to a fresh reel core is effected by pivoting said arms to move the reel apart from the rider roll to draw out a length of web between them, the rider roll remaining stationary, introducing a guide roller into the path of this length of web from the side opposite to the reel, moving the rider roll apart from the reel, further pivoting said arms to bring the fresh reel core into the path of the length of web between the guide roller and the rider roll in close proximity to the guide roller, and returning the rider roll to nip the web against the fresh reel core so that the web is caused to envelop the greater part of the periphery of the fresh reel core solely by two elements, namely the rider roll and the guide roller, and actuating a knife and transfer mechanism to cut the web between the fresh reel core and the guide roller and to transfer the leading end of the cut portion to be wound upon the fresh reel core.
Claim 3
Dependent Claim
58 words
A method according to claim 1, wherein the introduction of the guide roller deflects the web and causes the length of web between the guide roller and the reel to engage an idler roller mounted on the arms of the turnover stand close to the maximum circumference of the wound reel, which idler roller further deflects the web.
Claim 4
Dependent Claim
282 words
Apparatus for transferring a continuous running web of sheet material being wound onto a reel on to a fresh reel core, comprising a turnover reel stand having pivoted arms at the respective ends of which a reel and a reel core can be mounted and rotated, an idler rider roll having a pivotal mounting so as to be capable of riding upon the outermost winding of a reel mounted at the adjacent ends of the turnover stand arms, actuating means for pivoting the rider roll mounting, means for leading a web around the rider roll and on to the reel, a guide roller having a pivotal mounting, actuating means for pivoting the guide roller mounting, a knife and transfer mechanism associated with the guide roller mounting for cutting the web between the fresh reel core and guide roller and for transferring the leading end of the cut portion to be wound upon the fresh reel core, and control means for sequentially operating the parts of the apparatus so that for web transfer the turnover stand arms are rotated to move the reEl apart from the rider roll, the guide roller is introduced into the path of the web between the reel and rider roll in close proximity to the position to be assumed by a fresh reel core mounted at the other ends of the turnover stand arms on completion of 180* movement of the arms, the rider roll is moved away from said position, said 180* movement is completed, said rider roll is returned so as to cause the web to envelop the greater part of the periphery of the fresh reel core, and the knife and transfer mechanism is actuated.
Claim 5
Dependent Claim
282 words
Apparatus for transferring a continuous running web of sheet material being wound onto a reel on to a fresh reel core, comprising a turnover reel stand having pivoted arms at the respective ends of which a reel and a reel core can be mounted and rotated, an idler rider roll having a pivotal mounting so as to be capable of riding upon the outermost winding of a reel mounted at the adjacent ends of the turnover stand arms, actuating means for pivoting the rider roll mounting, means for leading a web around the rider roll and on to the reel, a guide roller having a pivotal mounting, actuating means for pivoting the guide roller mounting, a knife and transfer mechanism associated with the guide roller mounting for cutting the web between the fresh reel core and guide roller and for transferring the leading end of the cut portion to be wound upon the fresh reel core, and control means for sequentially operating the parts of the apparatus so that for web transfer the turnover stand arms are rotated to move the reEl apart from the rider roll, the guide roller is introduced into the path of the web between the reel and rider roll in close proximity to the position to be assumed by a fresh reel core mounted at the other ends of the turnover stand arms on completion of 180* movement of the arms, the rider roll is moved away from said position, said 180* movement is completed, said rider roll is returned so as to cause the web to envelop the greater part of the periphery of the fresh reel core, and the knife and transfer mechanism is actuated.
Claim 6
Dependent Claim
63 words
Apparatus according to claim 3, wherein further idler rollers are carried by the arms of the turnover stand, each in close proximity to the maximum circumference of an associated wound reel and trailing the associated reel with respect to the direction of rotation of the arms, said further idler rollers being arranged to engage the web between the guide roller and the reel.
Claim 7
Dependent Claim
34 words
Apparatus according to claim 5, wherein said control means are electro-pneumatic and cams disposed on the pivot shaft of the turnover stand arms are arranged to actuate switches controlling pneumatic cylinders in proper sequence.
