DEFINITION

Classification: 83/138

(under subclass 136) Device in which (a) the stripper or its mounting includes an elastic, resilient and/or flexible element, which element is compressed or extended during the cycle of operation, and whose tendency to return to its normal state urges the product away from the tool; or in which (b) the stripper is mounted on the tool or tool support

by means of a lost-motion connection (in which gravity acts on the stripper to urge the stripper into contact with the product as the tool is withdrawn).

(1) Note. An original patent for an elastic, rubberlike, resilient mounting for a nonelastomeric stripper will be found in this subclass (138).

SEE OR SEARCH THIS CLASS, SUBCLASS:

128, for a resiliently biased stripper which ejects a product from within a hollow cutter.

134, for a tool-synchronized stripper which is carried on an end of a spring arm.

142+, for a tool-synchronized stripper not carried by the moving tool or its support and which is biased against the product.
