Abstract
Abstract Apparatus for forming a score line of predetermined configuration in synthetic plastic sheet material includes a female die member having a slot corresponding to a desired score line, a male scoring member including a scoring rule movable against the sheet material to stretch it into the slot, and a resilient material frictionally engaging the sheet to immobilize the sheet between the members in those areas bordering the slot during score-forming. The resilient material extends along opposite sides of the rule and above its operable end. In one embodiment, the scoring member is of sufficient dimension to extend into the slot and compress the sheet material between the slot''s bottom and the end of the scoring rule.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
An apparatus for forming a score line of predetermined configuration in synthetic plastic sheet material, the apparatus comprising: a female die member and a male scoring member movable relative to one another into and out of score-forming relation, said female member having a surface with a slot for receiving said scoring member during score-forming, said scoring member having an end for locally stretching said sheet material into said slot during score-forming in order to form a score line in said sheet material without cutting completely through said material at said line, means for moving said member into score-forming relation, and means for immobilizing said sheet material between said members in those areas bordering said slot during said score-forming, said means for immobilizing comprising a resilient material which frictionally engages and immobilizes said sheet material.
Claim 2
Independent Claim
134 words
An apparatus for forming a score line of predetermined configuration in synthetic plastic sheet material, the apparatus comprising: a female die member and a male scoring member movable relative to one another into and out of score-forming relation, said female member having a surface with a slot for receiving said scoring member during score-forming, said scoring member having an end for locally stretching said sheet material into said slot during score-forming in order to form a score line in said sheet material without cutting completely through said material at said line, means for moving said member into score-forming relation, and means for immobilizing said sheet material between said members in those areas bordering said slot during said score-forming, said means for immobilizing comprising a resilient material which frictionally engages and immobilizes said sheet material.
Claim 3
Independent Claim
175 words
An apparatus for forming a score line of predetermined configuration in synthetic plastic sheet material which comprises: a female die member and a male scoring member movable relative to one another into and out of score-forming relation, said female die member having a surface with a slot therein for receiving said scoring member during score-forming, said scoring member including a scoring rule for urging said sheet material into said slot during score-forming in order to form a score line in said sheet material without cutting completely through said material at said line, said scoring member further including means for immobilizing said sheet material, said immobilizing means comprising a resilient material extending along opposite sides of said rule, and above the scoring end of the rule and having sufficient resiliency for compression below the rule end when said members are brought into score-forming relatiOn, said resilient material adapted to frictionally engage and immobilize said sheet material between said members in those areas bordering said slot during score-forming, and means for moving said members into score-forming relation.
Claim 4
Independent Claim
175 words
An apparatus for forming a score line of predetermined configuration in synthetic plastic sheet material which comprises: a female die member and a male scoring member movable relative to one another into and out of score-forming relation, said female die member having a surface with a slot therein for receiving said scoring member during score-forming, said scoring member including a scoring rule for urging said sheet material into said slot during score-forming in order to form a score line in said sheet material without cutting completely through said material at said line, said scoring member further including means for immobilizing said sheet material, said immobilizing means comprising a resilient material extending along opposite sides of said rule, and above the scoring end of the rule and having sufficient resiliency for compression below the rule end when said members are brought into score-forming relatiOn, said resilient material adapted to frictionally engage and immobilize said sheet material between said members in those areas bordering said slot during score-forming, and means for moving said members into score-forming relation.
Claim 5
Dependent Claim
34 words
The apparatus of claim 2 wherein said male member further comprises a cutting blade having two sides and a cutting end which cuts the sheet material when said members are moved into score-forming relation.
Claim 6
Dependent Claim
46 words
The apparatus of claim 3 further including resilient material extending along said cutting blade on both sides thereof and above the cutting end of said cutting blade, and having sufficient resiliency for compression below the cutting blade end when said members are brought into score-forming relation.
Claim 7
Dependent Claim
41 words
The apparatus of claim 2 wherein said slot has a bottom and wherein said scoring rule is of sufficient dimension so that its end extends into said slot during score-forming and compresses said sheet material between said end and said bottom.
