TH34947A - The process for the manufacture of non-leakproof inner tubes - Google Patents

Abstract

DC60 (18/11/46) The pre-finish material is a 2 'inner tube where the interior is divided into air chambers 3 and chambers for sealants 7 with partition 5. There were 41 air chambers provided in the wall surrounding the 4o sealant compartment and contacted the sealant channel 7. In the vulcanization process, the pre-finished material a 2 'inner tube was placed in the Heat mold 18 And high temperature gas And high pressure Flows into the seal chamber 3.This allows residual air in the seal cavity 7 Expelled via air outlet 41 while pressing against the wall 5 Attached to the wall surrounding the cavity for 4o-vulcanized sealant, the pre-fabricated 2 'inner tube is separated from the 18 heated moldings for sealant 7. Unable to expand Due to the presence of air chambers 41 and thus partition walls 5 cannot provide for expansion. That pushes the wall 5 Stretch out The wall surrounds the air cavity 4i. The pre-fabricated material is a 2 'inner tube, where the interior is divided into air chambers 3 and chambers for sealants 7.With partition 5, there are 41 air vents provided in the walls surrounding the 4o seal cavity. In the process of vulcanizing, the pre-finished material, a 2 'inner tube, was placed in a heated mold 18 and a high temperature gas. And high pressure This allows the residual air in the sealant cavity 7 to be expelled through the vent 41 while pressing the barrier 5 against the wall surrounding the sealant 4o. The pre-vulcanized object was a 2 'inner tube separated from the heated mold 18 chambers for sealant 7, unable to expand. Due to the presence of air chambers 41 and thus partition walls 5 cannot provide for expansion. That pushed the wall 5 to stretch out towards Wall surrounds air holes 41

Claims (3)

1.Processes for manufacturing in sealed containers Which has air vents (3) filled with air And a cavity for sealant (7) contained with sealant (8). Included with the first step Casting by extruding the pre-finished material into a wall (2 \ ') inner tube (4) with a circular cross section The pre-finished material, the inner tube (2 \ '), is divided the interior wall (4) into the air chamber (3) and the sealant (7) by the partition (5). Second Of connecting the opposite ends of the pre-finished object into the inner tubes (2 \ ') together to form the empty inner tubes as a ring. Third step Assembling the air discharge port (41) in the enclosing wall (4) where it connects to the sealant cavity (7). Fourth step. Pre-placement of an inner tube (2 \ ') in a heated mold (18) and m in that state. To empty the inner tube under the vulcanization with gas at temperature And high pressure Enter the air outlet (3). The fifth step. Adding sealant (8) to the cavity for sealant (7) and the sixth step. Closing the air outlet (41). 2. Process according to the nature of claim 1, where in the said fifth step, sealant (8) is added to the sealant compartment (7) through the air release port (41). ) 3. Process according to the nature of claim 1, where in the sixth step Mentioned It is a pre-clamping process of an object, it is a medicine in (2 \ ') with a raw rubber pad (19) placed on the aforementioned air outlet (41) between a pair of pressing parts (21,22). Pressed and welded together, and where one (21) press piece, which touches the bare inner tube on opposite sides of the raw rubber pad (19), is less than the hardness of the pre-finished material. Is an inner tube (2 \ ')
