ROTATION BODY OF PRINTING MACHINE WITH WORKING PART

FIELD: printing technologies. ^ SUBSTANCE: rotation body of printing machine with working part has main body and external body concentrically surrounding the main body, and also at least one channel for passage of thermostatting substance, provided with at least one input and one output, for thermal exchange of thermostatting environment with working part on the length between input and output of channel, where channel is open towards internal side of external body. In the channel at least on the aforementioned length an insert is positioned, thermally isolating thermostatting substance from main body. In a variant of realization, aforementioned channel is made in isolation material. According to another variant of realization, isolation material is made in form of a shell composed of shells tightly mounted in a row, fully enveloping main body in external material, where rotation body is made in form of shaft in paint machine. ^ EFFECT: increased efficiency of heat exchange between thermostatting substance and external body, effect of thermostatting substance during its passage through working part is maintained at approximately constant level. ^ 3 cl, 11 dwg
