Abstract: A lot forming device for forming separated lots of products which are coming off a first conveyor: The device comprising rotatable first and second circle sectors each on a respective drivable shaft and each having receptacles on its periphery for receiving products. A disk with peripheral receptacles is placed to receive the products from each of the sectors in turn. The disk is rotatable at a respective second shaft and delivers the separated lot of products to a following conveyor. The speeds of rotation of the sectors are controllable to separate the products into lots and to deliver them to the outlet conveyor at the selected speed. There may be a plurality of devices for arranging lots of the products in rows.

Abstract: An apparatus for forming, for their packing, lots of products fed by a conveyor and arranged in adjoining rows.The apparatus comprises a transfer chain or belt (1) stretched between two drive wheels (11, 12) having vertical axes (111, 121) and provided with uniformly spaced drive means (13), each intended to hold one carriage (2) comprising a movable holding and separating means (22) intended to form a lot (31) of products (3), one of the strands (10) of said chain (1) having two offsets (14, 15), the first of which (14), located at a short distance behind the feed wheel (12) for the carriages (2), makes it possible to disconnect them from the chain (1), while a roller (242) which is firmly attached to said carriage (2) engages in the groove (51) of a variable pitch screw (5) the axis of which is parallel to the straight line connecting the two points of offset (14, 15) and the length of which is approximately equal to the distance between said two points of offset (14, 15).
