Abstract

DC60 (10/06/40) A wrinkle-free and non-separating strip, even if present, is applied and adheres to the metal joint while being bent. The tape, made with a non-hardened rubber material, hardening accelerator, oxidizing agent, pigment, and bulk filler, is formed into an elongated shape with a top and bottom surface and a predetermined thickness measured in a direction perpendicular to the bottom or flat bottom surface. 1 The top surface forms a circular curved surface. 2 In cross-section, because the tape is in a non-hardened state, it can be freely bent when applied to the metal joint. After application of the tape to the metal joint, color is applied to the tape, which is followed by a heating process in which the tape is heated and hardened (see Figure 1). A wrinkle-free and non-separating strip, even if present, is applied and adheres to the metal joint while being bent. The tape, made with a non-hardened rubber material... The uncured material, curing accelerator, oxidizing agent, pigment, and bulk filler are formed into an elongated shape with a top and bottom surface and a predetermined thickness measured in a direction perpendicular to the bottom surface or a flat bottom surface.1 The top surface creates a circular curved surface.2 In cross-section, because the tape is in a non-cured state, it can be freely bent when applied to a metal joint. After application of the tape to the metal joint, color is applied to the tape, which is followed by a heating process in which the tape is heated and cured (see Figure 1).

Claims (9)

1. A long sealing strip for repairing deformed joints in vehicle body panels, restoring the deformed joint to its original, like-new condition. The strip is placed between a pair of metal surfaces or inner metal plates within a vehicle body panel. The sealing strip is applied to the joint after the deformation has been repaired. The strip is made of rubber and contains a hardening agent to allow it to bend at a right angle when applied to the joint. While the strip is not yet hardened, it has a predetermined thickness perpendicular to the lower surface and a curved upper surface. 2. The sealing strip as specified in Reputation 1, which is added to the uncured rubber material together with the curing catalyst, is an oxidizing agent. 3. Sealing strip, as specified in Claim 1, where adhesive shall be applied to the inferior surface of such sealing strip. 4. Sealing strip as specified in Claim 1, where; the aforementioned bottom surface is a stepped surface. 5. The method for producing sealing strips consists of three steps: the material preparation step, which involves preparing a sealing strip made of uncured rubber and a curing accelerator; the forming step, where the sealing strip is molded into a rectangular sheet while maintaining its uncured state; the gluing step, where an adhesive sheet is applied to the bottom of the rectangular sheet; and the cutting step, which cuts the rectangular sheet into at least one sealing strip, each considered to be a long rectangular shape with a defined bottom surface and thickness measured perpendicular to the bottom surface of the sealing strip. The rectangular sheet is moved while its top surface is brought into contact with a roller cutter equipped with at least a pair of curved blades spaced axially away from the annular notches created around the edge of the roller cutter. 6. Method for the production of sealing strips as specified in claim 5, where; the aforementioned annular concave section of the roller-type cutting machine has a circular curved shape in the cross-section. 7. The method for manufacturing the sealing strips as specified in Claim 5, whereby an oxidizing agent is added during the preparation of such sealing strip material. 8. The method for producing sealing strips consists of three steps: the preparation of the sealing strip material, which involves preparing a sealing strip made of uncured rubber and a curing accelerator; the forming of the sealing strip, in which the material is formed into a rectangular sheet while maintaining its uncured state; the gluing of the adhesive sheet, in which the bottom surface of the rectangular sheet is coated with adhesive; and the cutting of the rectangular sheet, in which the rectangular sheet is cut into at least one such sealing strip, each considered to be a long rectangular shape with a bottom surface and a defined thickness measured perpendicular to the bottom surface of the sealing strip, resulting in a rectangular cross-section. This rectangular sheet is moved while its top surface is brought into contact with a roller cutter equipped with at least a pair of curved blades spaced axially from an annular notch created on the edge of the roller cutter. This represents a depth greater than the specified thickness of the rectangular plate, and the longitudinal trimming procedure for trimming the opposite-length corners in the cross-section of the top surface of the sealing strip using a roller grinding method. 9. The repair method using sealing strips consists of the following steps: applying the sealing strip to the joint between a pair of metal surfaces or plates, securing the strip to the joint while bending it. The sealing strip is made from a rubber-based material containing a hardening agent. The strip is shaped to be elongated relative to the bottom surface, with a specified thickness measured perpendicular to the bottom surface. A color is then applied to the top surface of the bent and bonded sealing strip, which is then heated, causing the bent and bonded strip to harden into a final, flexible rubber product with a defined shape.
