摘要:
A disposable core structure supports a porous polymeric brush utilized in the treatment of substrates. The disposable core structure includes an exterior surface featuring a plurality of waffle-like recesses separated by walls having sufficient thinness to permit fabrication by injection molding. The core structure includes an end adapted to permit attachment to a rotating member of an associated substrate handling apparatus. The end of the core structure further includes an opening to a bore in fluid communication with pores on the exterior surface of the core structure. Injection molding allows economical mass production of the core structure, permitting it to be fitted with the polymeric brush in a clean room setting and then be permanently fixed to a single brush. This avoids problems of bunching, tearing, wrinkling and stretching associated with replacement of brushes in the field that requires the brush to be fitted around a conventional nondisposable core.
摘要:
A method and an apparatus for the manufacture of brushes, and brushes manufactured according to such method. A bristle carrier of a elastic material is provided with at least one substantially cylindrically elongated recess. An elongated bristle bundle is inserted into the elongated recess. The bristle bundle has a thickened portion at its insertion end with a transverse cross-section larger than the narrowest transverse cross-section of the recess. The longitudinal axis of the bristle bundle is aligned with the longitudinal axis of the recess, and a force is applied longitudinally on the thickened portion to cause a wall of the recess to elastically spring out so as to permit passage of the thickened portion. After passage of the thickened portion, the wall springs back until engagement of the wall on the bristle bundle occurs to secure the bristle bundle in the recess.

A flexible brush block is moved along a shape-retaining S-shaped handle whose curved end regions of opposite curvature are responsible for bending the flexible block and bristles that are supported thereon into either a generally concave or a convex configuration.
摘要:
A hair and massage brush in which each bristle is a bent loop projecting from a perforated support. The ends of the loops extend through perforations in the support and are fixed by fusing the ends into a ball of a size greater than a perforation of the support. When two bristles extend from each perforation, their four ends are fused into a single ball.

A hairbrush includes a plurality of concentric rings forming carrier plates for the bristles. The concentric rings are flexibly connected by hinges to allow the rings to move with respect to each other. The bristles carried by the concentric rings are stiff, allowing deep penetration of the hair. The flexibly mounted concentric rings allow the bristles to easily slip past any snags or knots encountered in the hair.
摘要:
A brush is described that includes a body, a carrier, a plurality of bristles and a frame. Each bristle is secured to the carrier and extends through a respective hole in the frame. The carrier deforms in response to pivoting of each bristle, and is held between the body and the frame at each bristle.
