Assembly for gathering card sliver for packaging thereof in cans of various size

An automatic device for gathering and packaging card sliver (3) in cans (4′, 4″), the said sliver being transferred from a card assembly (1) to a gathering assembly (20), which comprises a distributor (50, 50′) set over the top of the gathering can (4′, 4″) and eccentric with respect to the latter, driven by a motion of revolution, whilst the can (4′, 4″) set underneath is driven by a motion of rotation to distribute, in the can (4′, 4″), the sliver according to coils that translate their center according to circles that are coaxial with the can (4′, 4″), the said automatic device being characterized in that the gathering assembly (20) is made up of a plurality of gathering stations (21′, 21″) for specific gathering into cans of different size, there being provided in each workstation (21′, 21″) a gathering device specific for a given size of can and consisting of a rotary platform (35, 45) set underneath for rotation of the can (4′, 4″) receiving the sliver and of a distributor (50, 50′) driven by the motion of revolution, and in that the gathering assembly (20), in which the cans (4′, 4″) are alternatively employed, envisages a single common path (21, 21′, 22″, 22′″) for the various sizes of cans, the said path extending from an entrance to an exit, and is equipped with common members for imparting movement with rotating arms (22) and members for positioning the cans (4′, 4″) in the working position in their specific gathering station (21′, 21″), so that the sliver (3) produced by the card assembly (1) can be gathered alternatively, in one and the same gathering device (20), into large-sized cans (4′) or else into small-sized cans (4″) according to the requirements of use of the sliver in processes set downstream.
