Abstract
Abstract A multiple roller winding apparatus for the continuous winding of a continuously moving web of material. The material is wound onto take-up rollers which are fed from a magazine to driving rollers, and are disposed during the winding operation in a wedge formed between the driving rollers. A cutting means is provided for cutting the web of material when it reaches a predetermined diameter, and a feed means is utilized to start the web of material on a new take-up roller. An intake roller and an auxiliary winding roller are pivotably mounted on the winding apparatus and are movable between two different positions with respect to a stationary delivery roller so that in a first position a starting wedge is formed by the intake roller and auxiliary roller, and in the second position a wedge is formed between the intake roller and the delivery roller in order to complete the winding operation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
278 words
A multiple roller winding apparatus for continuously winding moving webs of material on winding spools, and including a supply magazine for supplying a plurality of winding spools on which the material is wound, and cutting means for cutting the web of material when a roll of material reaches a predetermined diameter, comprising: first mounting means, pivotably mounted at one end thereof, and movable between a first position in which said mounting means is disposed vertically and a second position in which said mounting means is disposed at an angle to said first position: a first drive roller, mounted on said mounting means; a winding roller, mounted on said mounting means parallel and adjacent to said first drive roller, said drive roller and winding roller forming a wedge therebetween for receiving the winding spools on which the webs of material are wound, and said drive roller engaging the webs of material wound on a winding spool when said mounting means is disposed in said first position so as to wind the webs of material thereon; a second drive roller, mounted on the winding apparatus parallel to said first drive roller and said winding roller, for engaging the webs of material wound on the winding spools when said mounting means is disposed in said second position, said first drive roller and said second drive roller forming a wedge therebetween for receiving the winding spools on which the webs of material are wound; and second mounting means pivotably mounted on the winding apparatus, and disposed above said wedge between said first and second drive rollers, for receiving the ends of the winding spools on which the webs of material are wound.
Claim 2
Dependent Claim
278 words
A multiple roller winding apparatus for continuously winding moving webs of material on winding spools, and including a supply magazine for supplying a plurality of winding spools on which the material is wound, and cutting means for cutting the web of material when a roll of material reaches a predetermined diameter, comprising: first mounting means, pivotably mounted at one end thereof, and movable between a first position in which said mounting means is disposed vertically and a second position in which said mounting means is disposed at an angle to said first position: a first drive roller, mounted on said mounting means; a winding roller, mounted on said mounting means parallel and adjacent to said first drive roller, said drive roller and winding roller forming a wedge therebetween for receiving the winding spools on which the webs of material are wound, and said drive roller engaging the webs of material wound on a winding spool when said mounting means is disposed in said first position so as to wind the webs of material thereon; a second drive roller, mounted on the winding apparatus parallel to said first drive roller and said winding roller, for engaging the webs of material wound on the winding spools when said mounting means is disposed in said second position, said first drive roller and said second drive roller forming a wedge therebetween for receiving the winding spools on which the webs of material are wound; and second mounting means pivotably mounted on the winding apparatus, and disposed above said wedge between said first and second drive rollers, for receiving the ends of the winding spools on which the webs of material are wound.
Claim 3
Dependent Claim
35 words
The winding apparatus as recited in claim 1, wherein said winding roller and said second drive roller are rotated at a rotational speed which is greater than the rotational speed of said first drive roller.
Claim 4
Dependent Claim
48 words
The winding apparatus as recited in claim 2, wherein said first mounting means comprises a pair of pivotable plates, pivotably mounted on the winding apparatus at one end thereof, said first drive roller and said winding roller being mounted at the other end thereof parallel to each other.
Claim 5
Dependent Claim
74 words
The winding apparatus as recited in claim 3, wherein said second mounting means comprises a pair of mounting arms, pivotably mounted on the winding apparatus vertically above said second drive roller, and including means for receiving the ends of the winding spools on which the webs of material are wound as the winding spools are rotated by said first and second drive rollers when said first mounting means is disposed in said second position.
Claim 6
Dependent Claim
69 words
The winding apparatus as recited in claim 4, further comprising means for directing a stream of pressurized air at the severed end of the web of material when the web is cut by the cutting means, and guiding said end upwardly around the winding spool disposed in said wedge between said first drive roller and said winding roller when said first mounting means is disposed in said first position.
Claim 7
Dependent Claim
35 words
The winding apparatus as recited in claim 5, wherein said cutting means comprises a blade carrier movable relative to said web and a plurality of cutting blades mounted on said carrier for movement relative thereto.
