Abstract
Abstract Apparatus for transferring a continuous web of sheet material being wound onto a fresh core employs a rider roll to press the web as it runs onto the new core and a guide roll to retain the web against the core circumferentially well downstream of the rider roll so that the web is wrapped around a major portion of the circumference. A cutter and transfer device are operable to cut the web between the core and the guide roll and urge the new leading end of the web onto the core.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A method of winding a continuous web of sheet material on to a plurality of reels in sequence, wherein the transfer of the running web to a fresh reel core is effected by leading the web between the fresh reel core and a rider roll which rides upon it and then over a guide roller positioned close to the core so that the web envelops the greater part of the periphery of the core, cutting the web between the core and the guide roller from the side that was outermost when traversing the core while supporting the web on the opposite side immediately ahead of the cutting position by a bar and pressing the web from said outermost side in a direction to move the cut web between the bar and the core to initiate a fold, and completing the fold back of the new leading end as the latter is directed into the nip between the core and the rider roll.
Claim 2
Independent Claim
162 words
A method of winding a continuous web of sheet material on to a plurality of reels in sequence, wherein the transfer of the running web to a fresh reel core is effected by leading the web between the fresh reel core and a rider roll which rides upon it and then over a guide roller positioned close to the core so that the web envelops the greater part of the periphery of the core, cutting the web between the core and the guide roller from the side that was outermost when traversing the core while supporting the web on the opposite side immediately ahead of the cutting position by a bar and pressing the web from said outermost side in a direction to move the cut web between the bar and the core to initiate a fold, and completing the fold back of the new leading end as the latter is directed into the nip between the core and the rider roll.
Claim 3
Dependent Claim
169 words
Apparatus for performing the method of claim 1, comprising a rider roll arranged to ride upon the fresh reel core, a guide roller movable into position close to the core so that a web can be run around the rider roll, the core and the guide roller so as to envelop the greater part of the periphery of the core, a knife and transfer assembly associated with the guide roller and mounted for cutting the web from the side that was outermost when traversing the core between the core and the guide roller and for directing the leading edge of the cut-off portion into the nip between the core and the rider roll and a back-up bar immediately ahead of the cutting position of the knife, on the opposite side of the web, the transfer assembly including means for pressing the web from said outermost side between the bar and said core to fold back the cut leading edge portion on itself as it is directed into the nip.
Claim 4
Dependent Claim
21 words
Apparatus as claimed in claim 2, wherein the pressing means comprises a blade with its leading edge directed towards the web.
Claim 5
Dependent Claim
27 words
Apparatus as claimed in claim 2, wherein the knife and transfer assembly also includes a brush for urging the web against the fresh core to increase traction.
Claim 6
Dependent Claim
19 words
Apparatus as claimed in claim 2, wherein the back-up bar is mountEd on support means for the rider roll.
Claim 7
Dependent Claim
24 words
Apparatus as claimed in claim 5, wherein the back-up bar is pivotally mounted to be removable away from the cutting position of the knife.
Claim 8
Dependent Claim
47 words
Apparatus according to claim 2, wherein the knife and transfer assembly is pivotally mounted on a pair of arms which also carry the guide roller and which are themselves pivoted for moving the guide roller and the knife and transfer assembly up to the fresh reel core.
