Abstract
Abstract An apparatus for pressing the edge of a laminate plastic sheet member against the edge of a base member causing the sheet member to adhere to the base member. A roller is rolled around the edge of the base member with the edge of the sheet member sandwiched therebetween thereby causing the edge of the sheet member to be rolled around the edge of the base member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
137 words
An apparatus for causing a sheet member to extend around the edge of a base member, said apparatus comprising: (a) a bed means for securely holding said base member; (b) roller means for rolling said sheet member around said edge of said base member as said base member is securely held by said bed means; and (c) drive means for causing said roller means to roll around said edge of said base member, said drive means including piston means for forcing said roller means against said edge of said base member as said roller means rolls around said edge of said base member, including a pressure regulator for controlling the extension of said piston means and for causing said drive means to be variable for allowing said apparatus to be used with base members of different thicknesses.
Claim 2
Independent Claim
137 words
An apparatus for causing a sheet member to extend around the edge of a base member, said apparatus comprising: (a) a bed means for securely holding said base member; (b) roller means for rolling said sheet member around said edge of said base member as said base member is securely held by said bed means; and (c) drive means for causing said roller means to roll around said edge of said base member, said drive means including piston means for forcing said roller means against said edge of said base member as said roller means rolls around said edge of said base member, including a pressure regulator for controlling the extension of said piston means and for causing said drive means to be variable for allowing said apparatus to be used with base members of different thicknesses.
Claim 3
Independent Claim
256 words
An apparatus for causing one edge of a laminate plastic sheet member to extend completely around one edge of a base member, said apparatus comprising: (a) a bed means for securely holding said sheet member and said base member, said bed means including clamp means for fixedly clamping said sheet member and said base member to said bed means with said one edge of said sheet member extending past said one edge of said base member; (b) heat means for heating said one edge of said sheet member as said sheet member securely held by said bed means; (c) roller means for rolling said one edge of said sheet member completely around said one edge of said base member as said sheet member and said base member are securely held by said bed means; and (d) drive means for causing said roller means to roll around said one edge of said base member, said drive means including pressure-applying means for forcing said roller means against said one edge of said base member with said one edge of said sheet member sandwiched therebetween as said roller means rolls around said one edge of said base member, said drive means being variable for allowing said apparatus to be used with base members of different thicknesses, said drive means including an arm means for pivotally securing said roller means with respect to said bed means, including a motor means, and including a screw means for being driven by said motor means and for raising and lowering said arm means.
Claim 4
Independent Claim
256 words
An apparatus for causing one edge of a laminate plastic sheet member to extend completely around one edge of a base member, said apparatus comprising: (a) a bed means for securely holding said sheet member and said base member, said bed means including clamp means for fixedly clamping said sheet member and said base member to said bed means with said one edge of said sheet member extending past said one edge of said base member; (b) heat means for heating said one edge of said sheet member as said sheet member securely held by said bed means; (c) roller means for rolling said one edge of said sheet member completely around said one edge of said base member as said sheet member and said base member are securely held by said bed means; and (d) drive means for causing said roller means to roll around said one edge of said base member, said drive means including pressure-applying means for forcing said roller means against said one edge of said base member with said one edge of said sheet member sandwiched therebetween as said roller means rolls around said one edge of said base member, said drive means being variable for allowing said apparatus to be used with base members of different thicknesses, said drive means including an arm means for pivotally securing said roller means with respect to said bed means, including a motor means, and including a screw means for being driven by said motor means and for raising and lowering said arm means.
Claim 5
Dependent Claim
89 words
The apparatus of claim 2 in which said arm means includes a first arm member having a first end and a second end and includes a second arm member having a first end and a second end, said first end of said first arm member being pivotally mounted with respect to said bed means, said second end of said first arm member being pivotally attached to said first end of said second arm member, said roller means being rotatably attached to said second end of said second arm member.
Claim 6
Dependent Claim
81 words
The apparatus of claim 3 in which said screw means is attached to said first arm member for raising and lowering said first arm member, and in which said pressure-applying means includes a pneumatic piston means positioned between said first and second arm members for causing said roller means to be held against said one edge of said base member with said one edge of said sheet member sandwiched therebetween as said screw means raises and lowers said first arm member.
