Abstract
A pressing roll for a tire building machine includes a shaft having a longitudinal axis; a plurality of discs inserted on the shaft in an axial series; a mounting arrangement for providing for an individual, radial displaceability of each disc relative to the longitudinal axis; and a force-exerting power arrangement for displacing the discs relative to the shaft.
Claims6
A pressing roll for a tire building machine, comprising
- (a) a shaft having a longitudinal axis, a substantially rectangular cross-sectional outline, opposite top and bottom sides and opposite lateral sides;
- said lateral sides having a length extending perpendicularly to said longitudinal axis;
- (b) a plurality of discs inserted on said shaft in an axial series;
- each said disc having an inner part, an annular outer part circumferentially surrounding said inner part and a ball bearing positioned between said inner and outer parts;
- said outer part being rotatable relative to said inner part;
- said inner part of each said disc including a substantially rectangular aperture having opposite top and bottom sides and two opposite lateral sides;
- said lateral sides having a length extending perpendicularly to said longitudinal axis;
- said shaft passing through said aperture;
- said length of said opposite lateral sides of said aperture being greater than said length of said opposite sides of said shaft;
- said opposite lateral sides of said aperture being slidable on said opposite sides of said shaft;
- said apertures forming part of said mounting means;
- (c) mounting means for providing for an individual displaceability of each said disc perpendicularly to said longitudinal axis;
- (d) force-exerting power means for displacing said discs relative to said shaft;
- (e) a cavity extending along said longitudinal axis and being defined by the apertures of the serially-arranged discs;
- (f) a top displacement chamber forming a part of said cavity and bounded by said top side of said shaft and said top side of the aperture of each said disc;
- (g) a bottom displacement chamber forming part of said cavity and bounded by said bottom side of said shaft and said bottom side of the aperture of each said disc;
- (h) top and bottom displacement hoses disposed in said top and bottom displacement chambers, respectively;
- and
- (i) pressurizing means for inflating said top and bottom displacement hoses by a pressurized fluid for displacing said discs relative to said shaft;
- said top and bottom displacement hoses and said pressurizing means forming said force-exerting power means.
