Abstract: An apparatus for transporting receptacles or the like in a filling and/or sealing machine has one or more endless conveyors or a turntable and several sets of locating members for individual receptacles or groups of receptacles. The selected locating member are separably coupled to the turntable or to discrete supporting plates on the conveyor or conveyors so that their sockets can accept individual receptacles for transport past one or more filling and/or other stations. If the machine is to treat differently dimensioned and/or configurated receptacles, the previously used locating members are replaced with a different set of locating members having sockets which can properly receive the newly selected receptacles for transport past one or more stations. Each locating member can be in a mere linear or in full surface-to-surface contact with the corresponding receptacle or receptacles. The selected locating members can be affixed to the upper side or underside of the turntable or to the upper sides or undersides of discrete supporting plates.

Abstract: Method and device for identification of a moving (v) material web (W;F;FF). A beam of light (I1) is directed at the material web by means of a transmitter device (21), said beam of light (I1) producing a beam of light (I2) reflected from the face of the material web (W;F;FF) to be identified. The latter beam of light (I2) is converted by a receiver device (31) into an electric signal (U2), on whose basis the presence, the quality, the condition, and/or the position of the material web (W;F;FF) is/are identified. The intensity of the beam of light (I1) transmitted from the transmitter (21) of light is regulated on the basis of the intensity of the reflected beam of light (I2). The reference level or levels of the electric identification signal derived from the reflected beam of light (I2) is/are adapted in compliance with the environment of operation so as to optimize the identification and to minimize interference from the environment. The device comprises a microprocessor (40), to which an analog signal is passed through an A/D converter (39). The microprocessor (40) controls the regulation unit (34) for the intensity of the light to be transmitted, said unit controlling an adjustable voltage source (23), from which a regulated operation voltage (U1) is supplied to the transmitter (21) of light. <IMAGE>
