Abstract
Abstract A web spooling machine with automatic spool changing equipment in which an empty spool is placed against the web between the feed roller and the full spool. Pivoting arms carry a cutter blade which cooperates with a pivoting anvil or counterblade to sever the web. At the same time, an elastic guide engages the severed end of the web to guide it over the new spool while a pressure roller keeps it in place. The cutter blade is propelled into the path of the moving web by a torsional spring which is wound up by a cam follower whenever the mechanism returns to its starting position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
In an apparatus for spooling webs which includes a base; spool holding means pivotably attached to said base for holding and for orienting at least one spool relative to said base; roller means, attached to arms pivoting on said base for engaging and displacing a web being wound up on one of said spools; the improvement comprising: cutter means pivotably attached to said shaft supporting said roller; said guide roller supported adjacent to the termini of said arms comprising a framework; energy storage means carried by said swivelable framework in proximity to said guide roller for powering the pivoting of said cutter means; and pivotable anvil means for cooperating with said cutter means to sever said web.
Claim 2
Dependent Claim
117 words
In an apparatus for spooling webs which includes a base; spool holding means pivotably attached to said base for holding and for orienting at least one spool relative to said base; roller means, attached to arms pivoting on said base for engaging and displacing a web being wound up on one of said spools; the improvement comprising: cutter means pivotably attached to said shaft supporting said roller; said guide roller supported adjacent to the termini of said arms comprising a framework; energy storage means carried by said swivelable framework in proximity to said guide roller for powering the pivoting of said cutter means; and pivotable anvil means for cooperating with said cutter means to sever said web.
Claim 3
Dependent Claim
50 words
An apparatus as defined by claim 1, further comprising: elastic web guide means, pivotably attached to said arms, the shape of said guide means substantially conforming to the contours of said spool when empty, for engaging said web after severing and for guiding the end thereof onto said empty spool.
Claim 4
Dependent Claim
50 words
An apparatus as defined by claim 2, further comprising: cam means, attached to said base, and cam follower means, affixed to said energy storage means; whereby, when said arms are pivoted, the cooperation of said cam means and said cam follower means transfers potential energy to said energy storage means.
Claim 5
Dependent Claim
29 words
An apparatus as defined by claim 3, wherein said energy storage means is a torsional spring and said cam follower means is a lever which twists said torsional spring.
Claim 6
Dependent Claim
48 words
An apparatus as defined by claim 1, in which said energy storage means comprises a transversely disposed torsional leaf spring member, one end of which is immovably mounted in one of said arms while the opposite end of said spring member is rotatably affixed to said other arm.
