Abstract
Abstract The present continuous web winding apparatus has first and second drive rollers for rotating a winding roller from a starting position through an intermediate position to an end position. Winding roller transfer and guide means are provided which form a guide channel at each end of the rollers for receiving journal studs of the winding roller. The guide channels are journaled, preferably to the shaft of the second drive roller, so that the guide channels and with the guide channels the journal studs of the winding roller may rotate about the second drive roller, whereby the studs may rise in these guide channels as the diameter of the winding roller increases toward its completion.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
137 words
In a continuous web winding apparatus wherein a first drive roller rotates a winding roller in a starting position, wherein a second drive roller is arranged for rotating the winding roller in cooperation with the first drive roller while the winding roller is in an intermediate position, and wherein the second drive roller rotates the winding roller while the latter is in an end position, the improvement comprising guide means for said winding roller positioned adjacent the ends of said rollers, journal means on the axis of said second roller and operatively connected to said guide means, and actuating means arranged for cooperation with said journal means for tilting said guide means back and forth about the axis of said second drive roller whereby the winding roller is transferred from said intermediate position to said end position.
Claim 2
Dependent Claim
137 words
In a continuous web winding apparatus wherein a first drive roller rotates a winding roller in a starting position, wherein a second drive roller is arranged for rotating the winding roller in cooperation with the first drive roller while the winding roller is in an intermediate position, and wherein the second drive roller rotates the winding roller while the latter is in an end position, the improvement comprising guide means for said winding roller positioned adjacent the ends of said rollers, journal means on the axis of said second roller and operatively connected to said guide means, and actuating means arranged for cooperation with said journal means for tilting said guide means back and forth about the axis of said second drive roller whereby the winding roller is transferred from said intermediate position to said end position.
Claim 3
Dependent Claim
