METHOD OF JOINING ENDS OF RUBBERIZED CLOTH TAPES

摘要

FIELD: materials handling facilities; belt conveyors. SUBSTANCE: proposed method comes to treatment of tapes, cutting of tape ends to form wedges, alignment of wedges, covering them with green rubber and subsequent curing. Summary length of side edges of wedges is determined on condition of equal strength of tape and joining from formula <EMI ID=0.1 HE=12 WI=26 TI=CHI> where k is joint strength factor 1.20 - 1.30; B is width of tape, mm; P is specific strength of tape, n/mm; Σdelta is summary thickness of cloth lining (core), mm; tautol is tolerable (tangential) stress of rubber, Mpa. EFFECT: provision of high strength of joint and increased service life of tape without repair. 3 cl, 1 dwg
