Abstract
An apparatus for collating dual-use filter sachets obtained from a flattened tube of thermally weldable filter paper comprising multiple bags or pouches defined by transverse thermal welds in continuously operating production machines and provided with labels, threads and tabs for attachment of the matter. The apparatus has a cutter for cutting up the tube, into portions having at least two pouches, across the attachment tabs. A device then folds in bellows-shape, these portions along the intermediate transverse thermal weld and operates in combination with a device having conveying pincers for conveying the folded bags to a pickup and transfer device through a fixed folder so as to set up the pouches back to back transferring them as thus folded to a welder for welding together the thus adjoining extremists thereof.
