Hand guided belt type sanding machine - has second stage of belt drive reduction driving onto reduced dia. in middle of driven roller

摘要

In conventional machines the two-stage belt reduction drive from the motor (11) is wholly on one side of the driven (20) and guide (24) rollers, increasing the width of the machine and moving thhe C of G to one side. This is avoided in the invention by having the second stage belt (19) driving onto a reduced dia. (23) in the middle of the driven pulley. The layshaft housing (16') and inside bearing (25) together with intermediate pulley (18) fit snugly into the space between the rollers (20,24). ADVANTAGE - Machine is slimmer and better balanced, improving handling and sanding quality.
