Abstract
Abstract An apparatus for affixing conveyor belt fasteners (12) to a conveyor belt (10) comprises locating device (54) for locating a plurality of fasteners at equally-spaced intervals with the legs (14, 16) of the fasteners embracing an edge of the belt. A fastener affixing arrangement (30) is movable stepwise by way of an advancing mechanism (118), and is adapted to deform the arms of a fastener onto the belt, to insert a staple (24) through the arms of the fastener and through the belt and to deform the ends of the staple projecting through the belt and through the arms of the fastener. In contrast to prior art devices, the affixing arrangement (30) and the advancing mechanism (118) are driven by an actuating arrangement having an input which is rotatable continuously in one direction in order to operate the apparatus.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
143 words
An apparatus for affixing fasteners, each comprising two arms Joined by an arcuate portion, to an end of a conveyor belt, comprising: locating means for locating a plurality of said fasteners at substantially equally-spaced intervals, with the legs of each of said fasteners embracing an edge of said conveyor belt; fastener affixing means for deforming the arms of a fastener onto said belt, for inserting a staple through the arms of said fastener and through said belt located between said arms and for deforming the ends of said staple projecting through said belt and through the arms of said fastener; advancing means for advancing said fastener affixing means stepwise; and an actuating mechanism for actuating said fastener affixing means and said advancing means and having an input shaft which rotates continuously in one direction to induce a cycle of operation of the apparatus.
Claim 2
Independent Claim
143 words
An apparatus for affixing fasteners, each comprising two arms Joined by an arcuate portion, to an end of a conveyor belt, comprising: locating means for locating a plurality of said fasteners at substantially equally-spaced intervals, with the legs of each of said fasteners embracing an edge of said conveyor belt; fastener affixing means for deforming the arms of a fastener onto said belt, for inserting a staple through the arms of said fastener and through said belt located between said arms and for deforming the ends of said staple projecting through said belt and through the arms of said fastener; advancing means for advancing said fastener affixing means stepwise; and an actuating mechanism for actuating said fastener affixing means and said advancing means and having an input shaft which rotates continuously in one direction to induce a cycle of operation of the apparatus.
