Abstract

The air feed channel (9) follows the drive shaft centre line and issues in the grinding roller inner cavity (10). This valve construction together with the rubber casing shaping (3) increases the air polishing roller range of use in that it is soft over the whole surface where the rubber casing goes against the grinding sheet. The polishing roller bottom can be made flat for polishing in corners and other places difficult of access.

Description

512 682 Beskrivning av medföljande ritning (1/1) På ritningen betecknas med (1) putsrullens spindel, med (2) dess drivaxel och med (3) den fastklämda gummihylsan. Denna är försedd med oríngar (4) och fastkläms med en bricka (5) och mutter (6) på putsrullens övre del och på putsrullens botten med bricka (7) och skruv (8). Lufttillförselkanalen betecknas med (9). Den följer drivaxeln för att mynna ut i håligheten (10) i rullens inre. En liten bit gummislang (11) fungerar som backventil och omsluter spindelns mittaxel (12) och tillika lufttillförselkanalens mynning som betecknas med (14). Slipdukshylsan betecknas med (13). 512 682 Description of the accompanying drawing (1/1) In the drawing, denote by (1) the spindle of the plaster roller, by (2) its drive shaft and by (3) the clamped rubber sleeve. This is fitted with rings (4) and clamped with a washer (5) and nut (6) on the upper part of the plaster roller and on the bottom of the plaster roller with washer (7) and screw (8). The air supply duct is denoted by (9). It follows the drive shaft to open into the cavity (10) in the interior of the roller. A small piece of rubber hose (11) acts as a non-return valve and encloses the center shaft (12) of the spindle and also the mouth of the air supply duct, which is indicated by (14). The abrasive cloth sleeve is denoted by (13).
