Patent ID: 7093333

Claim:
An improved structure of a fabric conveying guide rail to prevent the fabric from being contaminated by a guide screw is essentially comprised of a guide rail, a saddle, a setting nut, a locking sleeve, a guide screw, a structured square tube, and a separation plate; the saddle being located to the lower edge of the guide rail, the setting nut and the guide screw being placed from the side of the saddle; the saddle being made in a G-shape and a recess being reserved to a web of the saddle; a screw hole being each horizontally drilled on both sides of the outer wall of the recess; the locking sleeve being held in position by multiple tabs and slots provided to both sides of the setting nut; the saddle being locked up by the locking sleeve; the guide screw including right-handed thread and left-handed thread sections being mounted in the setting nut; two saddles being mounted in symmetry onto the structured square tube; the setting nut being locked horizontally to the recess of the saddle; a space being defined between the saddle and the top of the setting nut; a separation plate being locked to the outer wall of the saddle; and the separation plate being moved to force separating the fabric from contacting the guide screw; and the space allowing the guide screw to adjust the width between two guide rails.
