Abstract (en)

A coating apparatus for weft unthreaded textiles includes a deep grooved roll (20) to receive warps (C) of a weft unthreaded textile (S), and a shallow grooved roll (33) arranged downstream of said deep grooved roll to receive the warps arranged by the deep grooved roll. The apparatus further includes press-fitting means (46) for pressing the grooved roll (33) against a rubber sheet (6) on a calender roll (2) to force the warps in the shallow grooves into the rubber sheet, a restraining roll (52) rotatably arranged between the deep grooved roll and the shallow grooved roll and able to be in contact with a surface of the weft unthreaded textile, and urging means (54) for urging the restraining roll in a direction perpendicular to a surface of the weft unthreaded textile to change the moving direction of the weft unthreaded textile, thereby increasing a winding angle of the warps around the grooved roll (33) and preventing untwisting of the warps.
