Abstract
A chain link for a conveyor chain includes a planar elongate sheet metal conveying body having four outer corners and sides that extend between adjacent outer corners, the sides include long sides and short sides that extend between the long sides, the sides further include side face portions that extend substantially transversely to a conveying plane of the conveying body, and at each of the outer corners, the conveying body may include a corner face portion that extends transversely to the conveying plane and that connects angularly to a side face portion of a short side.

A chain link for a conveyor chain, comprising a planar elongate sheet metal conveying body having four outer corners and sides that extend between adjacent outer corners, the sides including a pair of opposing long sides and a pair of opposing short sides that extend between the long sides, the sides further including side face portions that extend substantially transversely to a conveying plane of the conveying body, and wherein at each of the outer corners, the conveying body includes a corner face portion that extends transversely to the conveying plane and that connects angularly to a side face portion of a short side.
A conveyor, comprising a series of hingedly connected chain links, each chain link comprising a planar elongate sheet metal conveying body having four outer corners and sides that extend between adjacent outer corners, the sides including a pair of opposing long sides and a pair of opposing short sides that extend between the long sides, the sides further including side face portions that extend substantially transversely to a conveying plane of the conveying body,
- wherein at each of the outer corners, the conveying body includes a corner face portion that extends transversely to the conveying plane, and that connects angularly to a side face portion of a short side.
A blank for a chain link, comprising a planar elongate sheet metal conveying body having four outer corners and sides that extend between adjacent outer corners, the sides including a pair of opposing long sides and a pair of opposing short sides that extend between the long sides, the sides including side face portions that extend substantially transversely to a conveying plane of the conveying body, further comprising planar tongues extending from the long sides of the conveying body along a conveying plane of the body, and
- wherein at each of the outer corners, the conveying body includes a corner face portion that extends transversely to the conveying plane, and that connects angularly to the side face portion of the short side.
Method of manufacturing a blank for a chain link for a conveyor chain,
- wherein the blank is punched from a strip of sheet metal by stamping sheet metal through a die with a punch tool, and
- wherein the punch tool is arranged to overlap a longitudinal side of the strip of sheet metal to form a long side face of a conveying body of the blank that extends transversely to the longitudinal side of the strip, so that
- a portion of the side face of the longitudinal side of the strip forms a short side face of the conveying body of the blank, and a corner face portion of the conveying body of the blank connects angularly with the short side face portion at a peripheral corner of the conveying body of the blank that is formed.
