Abstract
Abstract In stripping heat shrinkable sheathing material from an elongated metallic article, the material is scored along the length of the article. The article next is positioned in a nest defined by a pair of juxtaposed rollers and the material is heated so that it shrinks and separates along its scored portion. The rollers then are rotated to strip the material from the article and to discharge the material from the nest through the rollers, after which the stripped article is removed from the nest.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
The method of stripping heat shrinkable material which extends peripherally about a relatively rigid article, from the article, which comprises: scoring the heat shrinkable material for a substantial distance with respect to one dimension thereof; positioning the scored article in a nest defined by peripheral surface portions of a pair of juxtaposed stripping rollers; heating the scored heat shrinkable material after the article has been positioned in the nest so as to cause the material to shrink and to separate along the scored portion of the material; separating the material and the article by rotating the stripping rollers so that peripheral surface portions of the rollers adjacent the nest move toward one another to strip the heated material from the article and to discharge the material from the nest through the rollers; and removing the stripped article from the nest.
Claim 2
Independent Claim
140 words
The method of stripping heat shrinkable material which extends peripherally about a relatively rigid article, from the article, which comprises: scoring the heat shrinkable material for a substantial distance with respect to one dimension thereof; positioning the scored article in a nest defined by peripheral surface portions of a pair of juxtaposed stripping rollers; heating the scored heat shrinkable material after the article has been positioned in the nest so as to cause the material to shrink and to separate along the scored portion of the material; separating the material and the article by rotating the stripping rollers so that peripheral surface portions of the rollers adjacent the nest move toward one another to strip the heated material from the article and to discharge the material from the nest through the rollers; and removing the stripped article from the nest.
Claim 3
Dependent Claim
34 words
The method as recited in claim 1, in which the article is relatively elongated and in which: the heat shrinkable material is scored lengthwise of the article as the article is being fed longitudinally.
Claim 4
Dependent Claim
196 words
Apparatus for stripping heat shrinkable material which extends peripherally about an elongated relatively rigid article, from the article, which comprises: means for feeding the elongated article longitudinally; means for scoring the heat shrinkable material lengthwise of the article as the article is being fed longitudinally; a pair of juxtaposed stripping rollers having peripheral surface portions which define a nest for receiving the scored article, the spacing between said rollers being such that heat shrinkable material which is stripped from the article can pass therethrough, but such that the article cannot pass therethrough; means for feeding the scored article from said scoring means to the nest defined by said stripping rollers; radiant heat means for heating the scored heat shrinkable material after the article has been fed to the nest defined by said stripping rollers, such that the material shrinks and separates along the scored portion of the material; and means for rotating the stripping rollers so that peripheral surface portions of the rollers adjacent the nest move toward one another to strip the heated material from the article and to discharge the material from the nest through the rollers, thereby separating the material and the article.
Claim 5
Dependent Claim
196 words
Apparatus for stripping heat shrinkable material which extends peripherally about an elongated relatively rigid article, from the article, which comprises: means for feeding the elongated article longitudinally; means for scoring the heat shrinkable material lengthwise of the article as the article is being fed longitudinally; a pair of juxtaposed stripping rollers having peripheral surface portions which define a nest for receiving the scored article, the spacing between said rollers being such that heat shrinkable material which is stripped from the article can pass therethrough, but such that the article cannot pass therethrough; means for feeding the scored article from said scoring means to the nest defined by said stripping rollers; radiant heat means for heating the scored heat shrinkable material after the article has been fed to the nest defined by said stripping rollers, such that the material shrinks and separates along the scored portion of the material; and means for rotating the stripping rollers so that peripheral surface portions of the rollers adjacent the nest move toward one another to strip the heated material from the article and to discharge the material from the nest through the rollers, thereby separating the material and the article.
Claim 6
Dependent Claim
26 words
Apparatus as recited in claim 3, in which: said scoring means includes a rotatable support wheel and an opposed scoring wheel having a peripheral cutting edge.
Claim 7
Dependent Claim
85 words
Apparatus as recited in claim 3, which further comprises: a rotatable magazine member having a peripheral longitudinally extending slot for receiving a plurality of the scored articles therein from said scoring means; means for moving said magazine member from an article receiving position to an article discharge position over the nest defined by said stripping rollers; and means for rotating said magazine member to effect discharge of the scored articles from the slot in said magazine member into the nest defined by said stripping rollers.
Claim 8
Dependent Claim
168 words
Apparatus for stripping heat shrinkable material whiCh extends peripherally about a relatively rigid article, from the article, which comprises: means for scoring the heat shrinkable material on the article for a substantial distance with respect to one dimension of the material; juxtaposed rotatable stripping means having peripheral surface portions which define a nest for receiving and supporting the scored article; means for positioning the scored article in the nest defined by said juxtaposed rotatable stripping means; means for heating the scored heat shrinkable material after the article has been positioned in the nest defined by said juxtaposed rotatable stripping means, such that the material shrinks and separates along the scored portion of the material; and means for rotating said juxtaposed rotatable stripping means so that peripheral surface portions of said rotatable stripping means adjacent the nest move toward one another to strip the heated material from the article and to discharge the material from the nest through said rotatable stripping means, thereby separating the material and the article.
Claim 9
Dependent Claim
168 words
