Apparatus for splicing rubber coated cord fabric sections

An apparatus for splicing rubber coated cord fabric sections in which a continuous rubber coated parallel cord fabric strip having side edges is obliquely severed into rhomboidal cord fabric sections and said side edges are thereafter overlapped and spliced in regular succession into a continuous bias cord fabric strip, comprising:

• a bias-cutter conveyor including a conveyor for transferring said continuous cord fabric and a bias-cutter mounted on said conveyor for obliquely severing said cord fabric strip into rhomboidal cord fabric sections;
• a positioning mechanism for positioning each of said severed cord fabric sections to have obliquely severed edges orientated to a conveyance direction thereof with said side edges obliquely arranged to said conveyance direction thereof;
• a transfer mechanism positioned forwardly of said positioning mechanism for suckingly holding and intermittently transferring each of said cord fabric sections;
• a conveyor mechanism positioned forwardly of said transfer mechanism and including a plurality of endless belts running along the conveyance direction of said cord fabric with a predetermined space therebetween and having a number of air nozzles formed in a longitudinal direction thereof, a belt guide plate positioned inwardly of said endless belts and having a plurality of grooves each receiving and guiding said endless belt, a plurality of air pipes each pneumatically communicating with said grooves through a longitudinal slit formed at the bottom of each of said grooves, each of said air pipes having a rear portion rearwardly of the splicing mechanism with respect to the conveyance direction of said cord fabric section to be vacuumed and a remaining portion to be vacuumed and supplied with compressed air, and drive means for intermittently running said endless belts, whereby said cord fabric sections received from said transfer mechanism are transferred;
• and
• a splicing mechanism positioned above the longitudinally intermediate portion of said conveyor mechanism for pulling back a previously advanced cord fabric section to overlap and splice the trailing edge of said previously advanced cord fabric section on the leading edge of a subsequently advanced cord fabric section.
