Abstract

1,041,688. Grinding. RUBBER PLASTICS Ltd. June 14, 1965 [June 12, 1964], No. 24940/65. Heading B3D. [Also in Division B7] A protective strip for propeller blades is produced by passing a thin strip 2 of elastomeric homogeneous material, e.g. resilient polyurethane, between a grinding roller 7 and a former 6 having a flat portion 6<SP>111</SP> with inclined lateral portions 6<SP>11</SP> to cause the edge portions 2<SP>1</SP> of the strip to stand clear of the former, so that the edges of the strip are chamfered and roughened.
