Abstract

622,137. Vulcanizing long lengths. STEVENS, A. H. (Boston Woven Hose & Rubber Co.). Nov. 14, 1946, No. 33808. [Class 70] A method of feeding belting or the like into a trough-like channel formed in a rotating vulcanizing drum comprises passing the belting along a substantially straight path tangential to the channel, progressively bending the marginal portions of the belting to curve it transversely while moving the belting in said straight path and as it is being fed into the channel, and thereafter crowding the intermediate portion of the belting into the channel and its edge portions outwardly into contact with the side walls as the belting is fed into the channel. In a preferred apparatus for carrying out the invention the uncured belting 70 is passed in taut condition over roll 62 and then in a substantially straight path to the bite between the moulding channel in the drum 12 and the tension band 11, as it leaves the lower roll 15. At an intermediate point the belting is engaged by the roll 52 which bends the marginal portions inwardly towards; and feeds them into the moulding channel. Specification 500,925 is referred to.
