Abstract: A machine for forming filter bags for infusion products including a first movement carousel rotating continuously about a first axis of rotation; a plurality of first gripping means positioned along, and movable continuously with, the first carousel; a plurality of first operating stations positioned along, and movable continuously with, the first movement carousel; each first operating station is associated with a corresponding first gripping means; each first operating station is configured to operate on the piece of filter material in order to form, at least partly, a filter bag along a predetermined angular stretch of rotation of the first movement carousel; and a plurality of first translation devices, associated with the first movement carousel and configured for translating, mutually, the first operating stations and the corresponding first gripping means along a direction parallel to the axis of rotation.

Abstract: Disclosed are a method and a system (1) for arranging a plurality of articles moved in at least one mass flow (M1, M2). Articles designed identically in respect of an allocation feature (A, B, C) are fed to a separate buffer station (P1, P2, P3) from the at least one mass flow (M1, M2) and stored in the buffer station (P1, P2, P3). A specified compilation (Z1, Z2) of articles is then formed wherein stored articles are removed from one or more of the buffer stations (P1, P2, P3) in consideration of the specified compilation (Z1, Z2) and forwarded and/or guided to a handling station (10) in a defined sequence and/or arrangement.

Abstract: An article guide for a belt conveyor with belt-actuated guide walls. The guide is supported atop the conveyor belt on wheels that ride on the conveyor belt. At least one of the wheels is a drive wheel engaging one or more pushers that push conveyed articles along the belt's conveying surface. The pushers may be rollers rotated by or belts advanced by the drive wheel. The pushers form a moving vertical side wall of the guide.
