HEATER SYSTEM FOR CATHETER MANUFACTURING
20240019211 · 2024-01-18 ·

The invention is directed to a heating assembly for catheter manufacture which includes a heating element having a central vertical passage and a plurality of gas flow passages in communication with the central passage. The passages are at an angle relative to the central passage increasing heat transfer surface area. The invention may also include an iris assembly. The iris assembly includes a plurality of discs having slits which are offset relative to another disc. The invention may also include an insulation chamber surrounding the heating element. The flow of gas previously heated by the exterior of the thermos coupler and heating element is restricted by the insulation chamber for passage through the gas flow passages and into the central passage, so that the gas receives additional heat for exposure to sheathing material to be bound to a catheter.

METHOD AND APPARATUS FOR FORMING UNCURED RUBBER COMPONENT
20200130253 · 2020-04-30 · ·

A method for forming an uncured rubber component, the method includes conveying an uncured extruded rubber strip extruded continuously from an extruder using a conveyor, the conveyor including a first conveyor and a second conveyor located at a downstream side of the first conveyor in a convey direction, the step of conveying including shrinking the uncured extruded rubber strip, wherein the step of shrinking is such that the uncured extruded rubber strip, in a relaxed state of a U-shaped manner, passes through fluid held in a tank between the first conveyor and the second conveyor without being restrained so that the uncured extruded rubber strip shrinks freely while receiving buoyancy from the fluid, and cutting the uncured extruded rubber strip in a predetermined length to form an uncured rubber component, after the step of shrinking.

HEAT SHRINKABLE FILM AND METHOD FOR REPRODUCING POLYESTER CONTAINER USING SAME

Embodiments relate to a heat shrinkable film and a process for regenerating a polyester container using the same. The heat shrinkable film comprises a copolymerized polyester resin comprising a diol component and a dicarboxylic acid component and has a heat shrinkage rate of 30% or more in the main shrinkage direction upon thermal treatment at a temperature of 80 C. for 10 seconds and a melting point of 190 C. or higher as measured by differential scanning calorimetry. It not only solves the environmental problems by improving the recyclability of the polyester container, but also is capable of enhancing the yield and productivity.
