Abstract

1,272,045. Grinding. TIMESAVERS SANDERS Inc. 18 March, 1971 [11 Sept., 1970], No. 7206/71. Addition to 1,249,785. Heading B3D. A method of sanding a flat wooden surface of a workpiece B the grain of which runs lengthwise thereof, comprises training an endless abrasive belt 9<SP>1</SP> over a plurality of roles, one of which is a contact drum 11<SP>1</SP>, feeding the workpiece along a straight path with the abrasive belt pressed by the contact drum against the surface to be sanded along a narrow work performing zone parallel to the axis of the drum, and so relating the axis of the drum to the path of the workpiece that the narrow zone forms an angle of greater than 60 degrees and less than 75 degrees to the path of the workpiece. In apparatus for carrying out the method, workpieces B are fed by a belt conveyer 15 between mirror image upper and lower units 6, 7, each having an abrasive belt 9<SP>1</SP> trained about a driven contact roller 11<SP>1</SP> and an idler roller 10<SP>1</SP>. The upper unit is adjustably supported by hydraulic rams to vary the spacing between the contact rolls between which the workpieces are fed by upper and lower driven rollers 13<SP>1</SP>. The contact roller 11<SP>1</SP> is journaled in bearings 24 carried by a beam 25 fixed to the frame of the unit 6. The idler roller 10<SP>1</SP> is carried by a yoke 27 which is acted upon by a pneumatic cylinder 28 to tension the belt and is oscillated by a motor 29 to cause the belt to move to and fro axially of the contact roller through a distance equal to about one third of the width of the belt. The axis of the contact roller is disposed at 15 to 30 degrees less than squareness to the path of the work. The belt may be driven at 6000 s.f.p.m. and the workpieces fed at 800 f.p.m. The frequency of the to-and-fro movement of the belt may be between 20 and 30 per minute.
