Offset printing machine cylinder washer unit incorporates parking run verticalized when idle but horizontalized in line with working track for cloth changes etc and fitted with cover preventing access to live machine in cloth changes etc.

摘要

The guide has a parking run (6) which extends to the rear from where it joins the working run (4) and is at least as long as the washer unit (2). The unit runs on either run track (4 or 6) but in each case non-tippably mounted and separate from the other track (4 or 6). The run adjusts relative the working track (4) between working and idle positions, lining up with the run (4) when in use but pivoting round axis (22) standing normal to the working track to swing the parking run between idle and working positions. When working, the parking run extends horizontally as compared with idling in which case it (6) extends vertically. An access guard cover (30) pivots with the run track (6) so that when vertical the cover (30) prevents personnel access to the machine but when horizontal permits access to the washer unit for cloth duties etc. The cover swivel axis (34) lies spaced from and axi-parallel to the run track (6) axis (22).
