Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
Conveying apparatus comprising: a belt having a substantially flat top surface with at least one groove therein oriented longitudinally of the belt and generally perpendicular to a transverse horizontal axis of the belt; and extending from said substantially flat top surface to a position below said substantially flat top surface. at least one working element with a foot portion with at least one rib and a leading portion, the foot portion disposed against the top of the belt with the rib disposed in the groove; a fastener extending through a portion of the belt and only the leading portion of the foot portion in a direction generally normal to the groove; whereby the fastener, rib, and groove in the belt substantially (1) preclude the foot portion from pivoting at the top surface of the belt; and (2) do not inhibit belt bending.
Claim 2
Dependent Claim
