Abstract
Abstract A method and apparatus for repairing laminated material or cracked material includes preheated molds (30 and 130) which have cavities (34 and 134) shaped to generally conform to a given shape of a workpiece (20). Clamps (40, 41 and 42) apply pressure to the molds, and thereby the workpiece. In a preferred embodiment, the mold (30) has an auxiliary cavity (35). Adhesive may be injected into the mold cavity (134) to repair a delaminated workpiece and a patch adhesive to the mold cavity (34) to repair a crack.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
228 words
A method for repairing a cracked laminated portion of a window frame, the window frame having a first material laminated to a second material and separated therefrom, comprising: (a) preheating a first mold, the first mold having a cavity shaped to generally conform to the shape of an area of the window frame to be repaired; (b) forming a hole in the first material of the window frame proximate the area to be repaired so as to expose the second material; (c) injecting an adhesive through said hole, thereby placing adhesive between the first and second material; (d) placing the first mold over the area to be repaired; (e) applying a pressure to the first mold, thereby reforming any deformed area of the first material by heat, pressure and time; (f) removing the first mold; (g) placing a second mold over the area to be repaired the second mold having a cavity generally conforming to the window frame and an auxiliary cavity proximate the area to be repaired; (h) operatively connecting, by mechanical means, the first material to the second material proximate the area to be repaired; (i) applying pressure to the second mold and thereby the window; (j) injecting a patching adhesive to the auxiliary cavity of the second mold, wherein a patch is formed over the area to be repaired; and (k) removing the second mold.
Claim 2
Independent Claim
228 words
A method for repairing a cracked laminated portion of a window frame, the window frame having a first material laminated to a second material and separated therefrom, comprising: (a) preheating a first mold, the first mold having a cavity shaped to generally conform to the shape of an area of the window frame to be repaired; (b) forming a hole in the first material of the window frame proximate the area to be repaired so as to expose the second material; (c) injecting an adhesive through said hole, thereby placing adhesive between the first and second material; (d) placing the first mold over the area to be repaired; (e) applying a pressure to the first mold, thereby reforming any deformed area of the first material by heat, pressure and time; (f) removing the first mold; (g) placing a second mold over the area to be repaired the second mold having a cavity generally conforming to the window frame and an auxiliary cavity proximate the area to be repaired; (h) operatively connecting, by mechanical means, the first material to the second material proximate the area to be repaired; (i) applying pressure to the second mold and thereby the window; (j) injecting a patching adhesive to the auxiliary cavity of the second mold, wherein a patch is formed over the area to be repaired; and (k) removing the second mold.
Claim 3
Dependent Claim
24 words
The method of claim 1, wherein the operatively connecting by mechanical means is connecting the first material to the second material by a screw.
Claim 4
Independent Claim
291 words
A method for repairing a cracked laminated portion of a window frame, the window frame having a first material laminated to a second material and separated therefrom, comprising: (a) preheating a first mold, the first mold having a cavity shaped to generally conform to the shape of an area of the window frame to be repaired; (b) forming a hole in the first material of the window frame proximate the area to be repaired so as to expose the second material; (c) injecting an adhesive through said hole, thereby placing adhesive between the first and second material; (d) plugging the hole; (e) pressing on the first material to move the adhesive between the first material and the second material; (f) covering the area to be repaired; (g) placing the first mold over the area to be repaired; (h) applying pressure to the first mold, thereby reforming any deformed area of the first material by heat, pressure and time; (i) removing the mold, covering and any excessive adhesive; (j) operatively connecting, by mechanical means, the first material to the second material proximate the area to be repaired; (k) masking the area to be repaired; (l) placing a second mold over the area to be repaired the second mold having a cavity generally conforming to the window frame and an auxiliary cavity proximate the area to be repaired; (m) applying pressure to the second mold and thereby applying pressure to the window frame; (n) injecting a patching adhesive to the auxiliary cavity of the second mold, wherein a patch is formed over the area to be repaired; (o) removing the second mold, making material and any patching material; and (p) applying a finishing coat to the patch material to match the window frame.
Claim 5
Independent Claim

Claim 6
Dependent Claim
24 words
The method of claim 3, wherein the operatively connecting by mechanical means is connecting the first material to the second material by a screw.
