Abstract
Abstract A foil coiling apparatus is described wherein a plurality of pairs of spindles are mounted upon a rotating member and moved to four successive stations including an in-feed station for cores to be gripped by the spindles, an inspection station, and two coiling stations. Arcuate plates associated with each pair of spindles guides the leading edge of the foil about a core held between said spindles to initiate coiling of the foil upon the core. A reciprocating member at the first coiling station moves into and out of cooperation with each arcuate plate in succession to extend the guiding surface of said plates assist in initiating the wrapping of the foil about the core.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
255 words
An apparatus for coiling sheet material on a core from a supply of such material comprising means for supporting a core including at least one pair of axially aligned spindles, means for moving said spindles axially into and out of engagement with opposite ends of said core, means for rotating said spindles about their aligned axes when engaged with said core, rotating means for supporting and moving said spindles about an axis other then their aligned axes to at least two stations, said rotating means holding said spindles at each of said stations for a time before moving said spindles to the next succeeding station, two of said stations being coiling stations, an arcuate plate supported by said rotating means adjacent to and spaced from a core on said spindles, an inner guiding surface on said plate for guiding the end of a sheet about said core, means at one of said stations movable into and out of cooperation with said arcuate plate to extend the guiding surface of said arcuate plate to assist in guiding said sheet about said core to initiate the coiling thereof, said means for rotating said spindles operating at said first station to coil sheet material on said core to less than completion, said means for rotating said spindles completing the coiling of said sheet material onto said core at said second station, cut-off means adjacent said first station for cutting off the sheet of material being wound, and means at said second station to discharge said fully wound core.
Claim 2
Independent Claim
255 words
An apparatus for coiling sheet material on a core from a supply of such material comprising means for supporting a core including at least one pair of axially aligned spindles, means for moving said spindles axially into and out of engagement with opposite ends of said core, means for rotating said spindles about their aligned axes when engaged with said core, rotating means for supporting and moving said spindles about an axis other then their aligned axes to at least two stations, said rotating means holding said spindles at each of said stations for a time before moving said spindles to the next succeeding station, two of said stations being coiling stations, an arcuate plate supported by said rotating means adjacent to and spaced from a core on said spindles, an inner guiding surface on said plate for guiding the end of a sheet about said core, means at one of said stations movable into and out of cooperation with said arcuate plate to extend the guiding surface of said arcuate plate to assist in guiding said sheet about said core to initiate the coiling thereof, said means for rotating said spindles operating at said first station to coil sheet material on said core to less than completion, said means for rotating said spindles completing the coiling of said sheet material onto said core at said second station, cut-off means adjacent said first station for cutting off the sheet of material being wound, and means at said second station to discharge said fully wound core.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 including a plurality of pairs of spindles supported by said rotating member.
Claim 4
Dependent Claim
39 words
The apparatus according to claim 1 in which said cut-off means including a sharpened edge along one of the edges of the arcuate plate and a knife blade movable into and out of cutting relationship with said sharpened edge.
Claim 5
Dependent Claim
68 words
The apparatus of claim 2 in which there are four stations, one of said stations being an in-feed station for empty cores, another of said stations being an inspection station for inspecting for the presence of a core between a pair of spindles, and the other two stations being said previously mentioned coiling stations and in which each pair of spindles is moved in each station in succession.
Claim 6
Dependent Claim
85 words
The apparatus according to claim 4 in which each of said pairs of spindles has an arcuate plate associated therewith, each of said arcuate plates is brought successively, step-wise to said first coiling station, and said means movable into and out of cooperation with said arcuate plate moves into and out of cooperation with each of said arcuate plates in succession to extend the guiding surface of each said plate to assist in guiding said sheet about successive cores held between successive pairs of spindles.
Claim 7
Dependent Claim
42 words
The apparatus of claim 5 in which said cutoff means includes a sharpened edge on each of said arcuate plates and a knife movable into and out of cutting relationship successively with each of the said sharpened edges of said arcuate plates.
