The sealing roll includes a stationary internal shaft and an inductively heatable roll jacket supported with freedom to rotate around the shaft. A plurality of induction coils is wound around the shaft over ferrites, which are open to the outside. Cables for the induction coils are laid through a cable conduit in the shaft for connection to an external induction generator. A water cooling channel for indirectly cooling the induction coils is also arranged in the shaft. A cavity is formed in at least an axial subsection of the sealing roll between the roll jacket and the shaft, and at least part of a temperature detection device is arranged in the cavity or adjacent to the cavity so that an IR temperature sensor receives radiation emitted by the roll jacket and thus detects a temperature of the roll jacket.

Sealing roll

The device for sealing together a formed bottom sheet and a lidding sheet between a feed roll and a sealing roll has a heating unit for preheating the lidding sheet before the sealing operation. The heating unit is a contactless induction heating device which has coils and magnetic-field influencing elements which are arranged transversely to the travel direction of the lidding sheet and opposite at least one of the coils. The distance between each of the magnetic-field influencing elements and the at least one coil is adjusted by a control unit on the basis of measurement values of temperature sensors arranged downstream of the magnetic-field influencing elements in order to regulate the temperature profile of the lidding sheet.

Device for roll-sealing sheets

The device for transporting upright containers in a straight line includes a rake conveyor comprising multiple receiving sections for the containers and an opposing support element for the containers carried in the receiving sections. The rake conveyor is connected to two drives by at least two pivot systems, each with two arms, in such a way that the rake conveyor can be pushed back and forth both in the transport direction of the containers and also in the direction perpendicular to the transport direction of the containers.

The feeder for the controlled transfer of product items into the pockets of a web of sheeting has a base unit, a supply container for holding the product items, and a product conveyor for receiving the product items from the supply container. Further, the feeder has an exchangeable format unit including a sorting plate for receiving the product items from the product conveyor, a filling unit with a number of vertically extending filling tubes for receiving the product items from the sorting plate and with a blocking slide unit with a blocking slide plate for temporarily blocking the guiding channels of the filling tubes. The format unit further has a filling shoe for receiving the product items from the filling unit and for guiding them to the pockets of the web of sheeting. A plurality of drives and the corresponding electrical control components for moving the format unit, the sorting plate, the blocking slide plate and the filling shoe are arranged in the base unit.
