Profile coating extruder screw assembly and dismantling - uses components of profile holder or auxiliary tools to coaxially extract screw, profile guide tube and other parts

摘要

An extruder for coating profiled sections with rubber or thermoplastic has a hollow screw with which a guiding tube for the profile is located. A process for simplifying assembly and dismantling of the screw, guiding tube, drive wheel, etc. involves the use of the drive wheel etc. involves the use of the profile holder or auxiliary tools. Equipment for the assembly and dismantling is also claimed. The central guiding tube and screw may be withdrawn in either direction or the guiding tube can be withdrawn in the extrusion direction and the screw in the opposite direction. USE/ADVANTAGE - The process and equipment are for dismantling and assembling components of an extruder for coating profiles sections. Variable loads can be applied permitting esier assembly and dismantling and reducing machine cleaning time.
