Abstract
Abstract A bottle plate for receiving a bottle in a bottle-processing machine has a metal plate to which a flexible covering is adhered in order to satisfy high requirements regarding frictional contact between the covering and bottom of the bottle, granules of silicon carbide or corundum are embedded in the covering. These granules project into fissures in the microscopically uneven bottom of the bottle hook therein and thus fix the bottle to the disk against slip. The covering is flexible to promote this contact.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
107 words
In a bottle-processing machine wherein bottles are individually clamped against a bottle plate which is rotatable to rotatably entrain the bottle thereon, the improvement wherein said bottle plate comprises: a metal disk; and a flexible covering on an upper surface of said disk against which said bottle is pressed, a multiplicity of small hard sharp-edged frangible granules composed of a material selected from the group which consists of corundum, silicon carbide and mixtures thereof being embedded in said flexible covering and having projections exposed on a surface of the covering and engageable with a bottom surface of said bottle when said bottle is pressed against said covering.
Claim 2
Dependent Claim
107 words
