CONVEYOR APPARATUS
Document Type and Number:
WIPO Patent Application WO/2004/048248
Kind Code:
A1
Abstract:
A height (H) of a horizontal face of a tread step guide rail (3)(rail body (3a)) is set to a position obtained by adding a predetermined offset amount (&dgr ) to the height of a tangential line (L) at a driving sprocket (9). Further, a bend portion (13) is provided at an end portion of the tread step guide rail (3), on the introducing side of driving sprocket (9). As a result, the tread step guide rail (3) changes from the horizontal face to the bend portion (13) at a standard position nearest to the driving sprocket (9). This absorbs speed irregularity of a tread step roller that comes close to the driving sprocket (9).
