Abstract:
A holding device for holding plastic containers and in particular plastic parisons with a holding section which can be introduced into a mouth of the plastic containers, wherein the holding section has at least one first holding element and one second holding element which are movable relative to one another and which in each case have a section which can be applied to an inner wall of the mouth. According to the invention an expansion body which supports the two holding elements at least intermittently is disposed between the holding elements, wherein a replaceable expansion element is disposed on this expansion body, wherein this expansion element is located at least in some sections between the expansion body and the holding elements.
Abstract:
An apparatus for heating plastic preforms with a transport device which includes holding devices for holding the plastic preforms and wherein the transport path has at least one heating portion inside which the plastic preforms are heated, and with a heating device arranged stationarily at least in portions along the transport path and which heats the plastic preforms transported by the transport device during their transport through the heating portion, wherein the heating device has at least one in particular stationary applicator device which is configured for bombarding the plastic preforms with microwaves to heat them. In the heating portion, the transport device is arranged relative to the applicator device such that at least parts of the holding devices are arranged outside the applicator device, wherein the applicator device is configured to receive several plastic preforms simultaneously for at least some of the time.
Abstract:
Apparatus for heating plastic preforms, having a microwave generating device which generates microwaves, and having a resonator device which forms a receiving space into which the plastic preforms can be introduced so as to be acted upon by the microwaves in the resonator device in order to be heated, wherein the apparatus has a reflector element which is arranged at least partially in the receiving space and which is suitable and intended for conducting microwaves in the direction of a base region of the plastic preforms. According to the invention, the reflector element is movable relative to the receiving space and the apparatus has a drive device for moving the reflector element relative to the receiving space.
