Abstract
Stitchers for consolidating tire building components successively wrapped on a building drum comprise multiple thin or narrow annular discs in side-by-side array. Each is free independently and individually to rotate about an axis common to the discs in response to the rotation of the building drum, and to be displaced normal to such axis by differing radial elevation of the components relative to the surface of the drum. Uniformly distributed pressure of the discs on the components along the contact zone is obtained by an inflatable cushion extending through the discs and acting on them individually. Thin inner plates disposed respectively within each disc rotatably support the discs and transfer the stitching forces from the cushion to individual discs.
Claims11
A multiple disc stitcher for use in building tires comprising a pair of end assemblies spaced apart and disposed in parallel opposed relation to each other, a multiplicity of outer discs of equal exterior diameter and of concentric annular form and small thickness disposed in side-by-side array between the end members, each disc being slidable relative to the respectively adjacent disc, support means providing single continuous beam support for said discs disposed within the discs and extending normal to the discs between the end assemblies, a resilient fluid pressure containing cushion member juxtaposed to the support means and extending through the discs between the end assemblies and cooperable with the support means to control the displacement of the outer discs relative to the support means, a multiplicity of inner plate members each having an arcuate outer surface slidingly engageable with respectively associated one of said outer discs and small thickness corresponding to the thickness of the associated outer disc, said plate members each having an opening therethrough accommodating said fluid pressure containing member, said outer discs being freely rotatable relative to the support means and relative to said plate members.
