APPARATUS AND METHOD FOR CONTINUOUS MANUFACTURE OF A MINERAL WOOL PIPE SECTION FOR INSULATING PURPOSES

摘要

An apparatus for the continuous manufacture of a mineral wool pipe section for insulating purposes, said apparatus comprising a core and an outer roller assembly surrounding it at least partially, said roller assembly including at least two rollers, whereby a wool mat of designated length between the core and the roller assembly is windable around the core for forming a pipe section preform, one end of the core being clear for removing a formed pipe section from the core, as well as curing elements for curing the pipe section preform prior to a removal from the core off the core's clear end. At least a portion of the core is screw-shaped, the advancement of a formed portion of the pipe section along the core and finally off the core taking place in response to rotational motions of both the core's screw- shaped portion and the roller assembly.
