Clamp for retaining bristle bundles of various sizes
A method of exerting a uniform force on bristle bundles in a clamp. Holes in a locking plate in a clamp are adjusted such that when the clamp is engaged, a specific force is exerted on the bristle bundles. The adjustment allows the holes to be displaced by different amounts for a given displacement of the locking plate.
