Claim 1
Independent Claim
236 words
A method for manufacturing plastic name tag holders on a dielectric sealing machine comprising the following steps: a. placing a bottom plastic sheet on the lower platen of the sealing machine; b. overlying the bottom plastic sheet with at least one horizontal insert finger having a substantially U-shaped horizontal perimeter; c. placing a top plastic sheet over the insert finger; d. contacting the upper surface of the top sheet with a compression block to press said top sheet horizontally against the insert finger; e. maintaining the compression block in engagement with the upper surface of the top sheet while contacting said top sheet with a horizontal substantially U-shaped electrode die, the substantially U-shaped inner periphery of said die being slightly wider than the substantially U-shaped perimeter of the insert finger, said die and said insert finger being in vertical telescopic registration, said die drawing said top sheet downwardly around the perimeter of said insert fingers and out wardly against the horizontal upper surface of the bottom sheet, said electrode die electronically sealing the top and bottom sheets together around the periphery of said insert finger; and f. raising the electrode die from the top sheet and removing the completely sealed name tag holder from the insert finger, said name tag holder having a cavity formed by said insert finger between the top and bottom sheets in which the top sheet is parallel to the bottom sheet.
Claim 2
Independent Claim
236 words
A method for manufacturing plastic name tag holders on a dielectric sealing machine comprising the following steps: a. placing a bottom plastic sheet on the lower platen of the sealing machine; b. overlying the bottom plastic sheet with at least one horizontal insert finger having a substantially U-shaped horizontal perimeter; c. placing a top plastic sheet over the insert finger; d. contacting the upper surface of the top sheet with a compression block to press said top sheet horizontally against the insert finger; e. maintaining the compression block in engagement with the upper surface of the top sheet while contacting said top sheet with a horizontal substantially U-shaped electrode die, the substantially U-shaped inner periphery of said die being slightly wider than the substantially U-shaped perimeter of the insert finger, said die and said insert finger being in vertical telescopic registration, said die drawing said top sheet downwardly around the perimeter of said insert fingers and out wardly against the horizontal upper surface of the bottom sheet, said electrode die electronically sealing the top and bottom sheets together around the periphery of said insert finger; and f. raising the electrode die from the top sheet and removing the completely sealed name tag holder from the insert finger, said name tag holder having a cavity formed by said insert finger between the top and bottom sheets in which the top sheet is parallel to the bottom sheet.
Claim 3
Dependent Claim
55 words
The method of claim 1 wherein a plurality of insert fingers are mounted on a common hinge which is secured to the underlying lower platen, said insert fingers hinging upwardly to permit the bottom plastic sheet to be placed on said lower platen and said insert fingers hinging downwardly to overly said bottom plastic sheet.
Claim 4
Dependent Claim
23 words
The method of claim 1 wherein the sealing step is performed over a time period within the range of 8 to 11 seconds.
Claim 5
Dependent Claim
35 words
The method of claim 1 wherein said electrode die seals the top and bottom sheets together by simultaneously heating them with a relatively constant heat and by electronically energizing them with a radio frequency signal.
Claim 6
Dependent Claim
24 words
The method of claim 1 further characterized by the step of vertically slotting the overlying top and bottom sheets to accommodate a fastening strap.
Claim 7
Dependent Claim
24 words
The method of claim 1 further characterized by the step of printing advertising or the like on the lower surface of the bottom sheet.
Claim 8
Dependent Claim
40 words
The method of claim 1 wherein said electrode die has a peripheral substantially U-shaped outer cutting edge in addition to the peripheral substantially U-shaped inner sealing edge, said cutting edge cutting said top and bottom sheets during the sealing step.
Claim 9
Dependent Claim
24 words
The method of claim 7 wherein after cutting, the remaining top and bottom sheet scrap is stripped away manually in a single tearing motion.
Claim 10
Dependent Claim
27 words
The method of claim 1 wherein during the sealing step the electrode die is heated to a constant temperature in the range of 110° to 120° C.
Claim 11
Dependent Claim
35 words
The method of claim 9 wherein the sealing step is followed by a cooling step, said sheets being cooled during said cooling step over a time period within the range of 1 to 2 seconds.
Claim 12
Dependent Claim
21 words
The method of claim 1 wherein during the sealing step the electrode die is electronically energized with a radio frequency signal.
Claim 13
Dependent Claim
22 words
The method of claim 11 wherein the strength of the radio frequency signal gradually increases and then decreases during the sealing step.
