DEVICE FOR REPOSITIONING AND ADJUSTING FEEDING ROLLERS LOCATED IN TUBULAR CROSSPIECES Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: feeding rollers are adapted for conveying sheets to side-cut shears or to shears for cutting sheets into measured portions or for cutting sheets in transverse direction. Cross-pieces are suspended in shears frame through bearing bodies for deflection about fixed axis transversely of sheet passage plane and for repositioning relative to sheet. At least one bearing body has members for horizontal and/or vertical repositioning and adjustment of cross-piece. Device has wedge-shaped members movable within bearing body between cross-piece of feeding roller and bearing body. Repositioning members are coupled with adjusting members. Wedge-shaped members may be coupled with lead screws disposed outside cross-piece or on bearing body. Lead screws with leaf springs are positioned in bearing body to allow adjustment of cross-piece to be provided. Bearing body is made V-shaped, with open side of bearing body being closed by removable cover. EFFECT: efficient adjustment of feeding rollers and enhanced reliability in operation. 4 cl, 2 dwg
