Abstract: A tire building apparatus comprising an expandible former embodying axially movable former expanding and contracting means to dispose the former in positions defining firm supporting surfaces of different radii, said expanding and contracting means ensuring symmetrical expansion and contraction of the former with respect to a transverse plane of the former. Axially-movable tire bead core locating and supporting means are disposed on opposite sides of said transverse plane. Further means, for example at least one rack and pinion mechanism connecting the two bead core locating and supporting means, is provided to ensure that axial movements of the two bead core locating and supporting means occur symmetrically with respect to said transverse plane.
Abstract: A sickle guard having at least one longitudinally extending guard finger for use in a mower having sickle means including mounting means for supporting flat cutter sections for movement transversely of the guard finger, wherein the guard finger has a bottom body portion having an upper ledger surface lying in a horizontal plane and have cutting edges at each of the sides thereof, trash bar means extending transversely at the rear of the cutting edges of the ledger surface and in which the trash bar means has upper horizontal surface means lying in the horizontal plane of the ledger surfce of the guard finger and having cutting edge means at the forward end thereof, and in which the ledger surface and the upper surface of the trash bar means provide for supporting the cutter sections of the sickle means for movement with respect to the guard finger and in cutting relation to the cutting edges of the ledger surface and the cutting edge means of the trash bar means.
Abstract: A tire breaker is formed from a cord on a gum base supported on a work belt. A rotor member is mounted above the work belt, and includes inner and outer cord engaging and laying means. Upon intermittent rotation of the rotor member, the cord engaging and laying means engage the cord, fold the same into successive side-by-side loops, and lay the loops on the gum base.
Abstract: Apparatus for curing solvent-free inks, coatings and the like in which the apparatus includes moving work, conveyor means for the moving work, an assembly including ultraviolet producing source and reflector partially encasing the ultraviolet producing source and adapted to reflect the radiant energy from the ultraviolet producing source toward the moving work, closable shutter means for blocking the radiant energy from the ultraviolet producing source from impinging upon the moving work when the operation of the system is temporarily interrupted. The reflector, the shutter means, as well as the conveyor, are provided with a plurality of spaced heat pipes contiguously affixed thereto and adapted to cool these elements.
Abstract: A stitcher assembly for use in tire building apparatus which apparatus has main frame means and rotatable tire building drum means supported by the main frame means and in turn supporting tire carcass material along with partially applied tread cap and/or sidewall components. The stitcher assembly includes a pair of carrier units, means for supporting and rotating the carrier units relative to the main frame means, a pair of arm assemblies one associated with each of the carrier units and having stitcher wheel means, and means for supporting and linearly moving the arm assemblies within the carrier units.
