PCT No. PCT/EP95/01592 Sec. 371 Date Jun. 9, 1997 Sec. 102(e) Date Jun. 9, 1997 PCT Filed Apr. 26, 1995 PCT Pub. No. WO95/29858 PCT Pub. Date Nov. 9, 1995The invention relates to an apron conveyor whose mutually overlapping members, consisting of plates with side walls which connect vertically, are arranged on link chains and are partitioned in a way matching the chain divisions. The slats are provided in their overlap area on their oblique edges on one hand with a limb which points upwards away from the plane of the slat and, on the other hand, with an arched recess which covers the raised limb of the adjacent slat. According to the invention, webs connected to the side walls or formed by them are provided along the length of the side walls. These webs connect the chain links laterally. This arrangement allows the use of standardised link chains of which only one in each link pair must be provided with two holes (in particular threaded holes) for connection of the members to the webs. The chains can be fitted at the outer edge of the slats as far from each other as possible, so that the chains shift towards the immediate vicinity of the rolls which support the slat conveyor and the members are subjected to a minimum of bending strain. It is also possible to arrange the chain wheels in the immediate vicinity of the shaft bearings, so that the bending strain on the chain wheel shaft can also be kept low. In a further embodiment, axial bolt holders mounted on the webs to the side walls and facing the chain links can, together with the chain links, be connected to the webs.
