(20) is assembled to the door trim (25).

그리고 웨더 스트립 본체의 제조공정은 도 8에 도시한 바와 같이, 보강심(23)을 롤 성형하는 공정과, 상기 보강심(23)을 금형내에 인써트하고, 고정부(21)는 폴리 비닐 클로라이드(PVC) 등의 경질플라스틱으로, 고정부(21)의 상부노출면과 밀폐립(22)은 써모 플라스틱 에라스토머(Thermo Plastic Elastomer, TPE) 등의 올레핀계 플라스틱에 의하여 이중압출하여 웨더 스트립 본체(20)를 압출성형하는 공 정과, 상기 압출성형한 웨더 스트립 본체(20)의 칫수를 안정화하는 사이징공정과, 상기 밀폐립(22)에 파일을 접착하는 플로킹형성공정과, 상기 보강심(23)을 직각으로 타발성형(Lancing)하여 고정편(24)을 성형하는 공정과, 일정길이로 절단하는 절단공정과, 상기 절단공정에서 양단에 노출된 보강심(23)의 녹 발생을 방지하기 위한 방청공정 순으로 제조한 것이다.In the manufacturing process of the weather strip main body, as shown in Fig. 8, the step of roll forming the reinforcing core 23, the reinforcing core 23 is inserted into the mold, and the fixing portion 21 is made of polyvinyl chloride ( A hard plastic such as PVC), and the upper exposed surface of the fixing part 21 and the sealing lip 22 are double-extruded by an olefin-based plastic such as Thermo Plastic Elastomer (TPE) and the weather strip body ( 20), a sizing process of stabilizing the dimensions of the extruded weather strip body 20, a flocking forming process of adhering a pile to the hermetic lip 22, and the reinforcement core 23 Forming a fixing piece 24 by punching at a right angle, cutting a cut to a certain length, and rust prevention to prevent rust of the reinforcing cores 23 exposed at both ends in the cutting step.

미설명부호 28은 도어 글래스이고, 29는 도어 아웃터 패널이며, 30은 도어 인너 패널이다.Reference numeral 28 is a door glass, 29 is a door outer panel, and 30 is a door inner panel.

그러나 상기한 도어 인사이드 벨트 웨더 스트립은 아래와 같은 문제점이 발생하고 있다.However, the door inside belt weather strip has the following problems.

첫째, 웨더 스트립 본체(20)는 연강제 박판 등을 롤 성형한 보강심(23)을 인써트하여 압출성형한 후 고정편(24)을 타발성형하여야 함으로 재료비가 고가로 되고, 성형 및 타발공정이 복잡하여 원가가 상승되며, 재생이 불가능하게 된다.First, the weather strip main body 20 is formed by inserting the reinforcing core 23 roll-molded thin steel sheet or the like and then extrusion molding, so that the fixing piece 24 needs to be punched, so that the material cost is high, and the molding and punching process is performed. The complexity is high and the cost is impossible.

둘째, 보강심(23)에 형성한 고정편(24)을 지지편(26)에 형성한 지지공(27)에 삽입한 후 고정편(24)을 구부려야 함으로 웨더 스트립 본체(20)의 조립공정이 복잡하다.Second, assembling the weather strip body 20 by inserting the fixing piece 24 formed in the reinforcing core 23 into the support hole 27 formed in the supporting piece 26 and then bending the fixing piece 24. The process is complicated.

셋째, 웨더 스트립 본체(20)의 보강심(23)에 형성한 고정편(24)을 지지편(26)에 형성한 지지공(27)에 삽입 조립할 때 조립공차 등이 발생하기 때문에 이를 극복하기 위하여 지지공(27)의 단면적을 크게 형성하여야 함으로써, 웨더 스트립 본체(20)를 도어 트림(25)의 지지편(26)에 조립한 후 상하 및 도어와 직각방향으로 유동하여 소음 등의 차단기능이 떨어지고, 웨더 스트립 본체(20)가 상하 및 도어와 직각방향으로 유동하면 도어 글래스(28)의 승강시에 밀폐립(22)이 도어 글래스(28)에서 들뜨거나 끼임이 발생함으로 소음차단 기능이 떨어질 뿐 아니라 소음이 발생하며 밀폐립(22)과 도어 글래스(28)의 마찰이 커짐으로 작동감이 떨어지고 도어 글래스 승강수단 등의 고장을 일으킨다.Third, when the fixing piece 24 formed on the reinforcing core 23 of the weather strip body 20 is inserted into the support hole 27 formed on the support piece 26, an assembly tolerance or the like occurs to overcome this problem. In order to form a large cross-sectional area of the support hole 27, the weather strip main body 20 is assembled to the support piece 26 of the door trim 25, and then flows up and down and at a right angle with the door to block noise. And the weather strip body 20 flows up and down and at right angles to the door, the sealing lip 22 is lifted or pinched from the door glass 28 when the door glass 28 is lifted and lowered. Not only fall, noise is generated, the friction between the sealing lip 22 and the door glass 28 is increased, the operation feeling is reduced, causing the failure of the door glass lifting means.
