Abstract: In a method for forming product stacks of folded or unfolded product blanks made of paper or chemical pulp, product blanks are supplied consecutively to a stacking surface and placed in an upright position. A separating element is inserted between two consecutive product blanks as the product blanks are moved against a channel wall of a discharge channel for temporary support of a rear side of the product blanks, to thereby form a first product stack with a predetermined number of product blanks between the separating element and the channel wall. The channel wall is opened to thereby allow the first product stack to be transferred to the discharge channel, and a sliding element is inserted between the product stack and a subsequent second product stack, as the first product stack is moved to the discharge channel.

Conveyor drum includes a separation device for changing a longitudinal axial spacing of the articles by a predetermined longitudinal axial separation, and an adjustment device structured and arranged to adjust the predetermined longitudinal axial separation. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: The invention relates to a method for producing multi-segment filters for the tobacco processing industry, wherein filter rods or filter segments are delivered to a form a group of filter segments. The method includes introducing a medium into the filter rods or filter segments before the filter rods or filter segments are delivered to the formed group of filter segments. The invention also relates to a module of a multi-segment filter machine for the tobacco processing industry, wherein filter rods or filter segments can be delivered to form a group of filter segments. The invention further relates to a multi-segment filter machine for the tobacco processing industry.

Abstract: A method and arrangement are provided for producing compound filters for products in the tobacco-processing industry. A filter tube, having a filter element in a central region of the filter tube, is supplied to a predetermined position. Predetermined portions of filtering material are then inserted into the filter tube from at least a first end of the filter tube so that filter segments form in at least a first part of the filter tube.

Abstract: A method and apparatus for producing multi-segment filter elements in the tobacco-processing industry. The multi-segment filter elements each include a first filter segment and at least one second filter segment. A sleeve element is arranged in the first filter segment. The second filter segment is inserted into the sleeve element in the first filter segment and the sleeve element is pulled out.

Abstract: Process and device for measuring bar-shaped articles. The process includes conveying the bar-shaped articles in a conveyor line, and optically measuring at least one physical property of the bar-shaped articles. The device includes an optical measuring device structured and arranged to measure at least one physical property of the filter bars. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: Process and device for assembling groups of filter segments in a rod process. The process includes providing a plurality of different types of filter segments, assembling the plurality of different types of filter segments into a group of filter segments, and dividing the group of filter segments into at least two part groups of filter segments. The filter segments of each part group adjoin each other in a lengthwise axial manner. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: Cigarettes or other rod-shaped articles of the tobacco processing industry are transported sideways from a source along an elongated horizontal path into at least one downwardly extending second path. If the inlet of a second path is to be sealed from the adjacent outlet portion of the horizontal path, a partition is moved across the inlet in the general direction of advancement of articles along the first path. The partition includes a carrier which is reciprocable along a slightly upwardly and forwardly inclined track, and a flexible belt which is tensioned by one or more springs and is trained over the leader of the carrier. A variable-capacity reservoir is located above the horizontal path opposite the inlet of each second path to accept some of the articles which are being moved back into the first path in response to movement of the partition across the inlet of the adjacent second path.

Abstract: An apparatus for transporting a mass flow of rod-shaped articles of the tobacco processing industry from a first station to a remote second station has two coaxial upright helical tracks one of which extends from the first station and the other of which extends from and is at least close to the second station. One or more endless chain or belt conveyors are provided to advance the articles of the mass flow along an elongated path which is defined in part by the first and in part by the second track. The apparatus can be used as a variable-capacity first-in first-out reservoir for rod-shaped articles due to the provision of one or two bridges. If the apparatus employs a single bridge and first and second conveyors, the bridge carries a first conveying device which receives articles from the first conveyor serving to accept articles at the first station, and a second conveying device which receives articles from the first conveying device and transfers the thus received articles onto the second conveyor.

Abstract: A chain conveyor for the transport of mass flows of cigarettes or other rod-shaped commodities has a series of identical links which are articulately connected to each other by alternating vertical and horizontal chain pins. The upper portions of the vertical pins carry platforms having supporting surfaces for the commodities, and each vertical pin further carries roller followers serving to track vertically spaced-apart portions of a guide surface which can have one or more non-linear portions, such as convex portions. The leading and trailing portions of successive platforms are interdigitated in such a way that the supporting surfaces of neighboring platforms can be inclined relative to each other as well as that the supporting surfaces of neighboring platforms can turn relative to each other about the axes of the respective vertical pins. Portions of the horizontal pins can extend into a channel between the vertically spaced-apart portions of the guide surface.

Abstract: A unit which serves to fill trays with surplus cigarettes adjacent the path of movement of a mass flow of cigarettes from a maker to a processing machine is disposed at a level beneath a unit which empties the contents of filled trays into the mass flow when the requirements of the processing machine exceed the output of the maker. Each unit stores empty trays at an upper level and filled trays at a lower level. The two units are adjacent a device which serves to transfer trays between the storeys as well as between the two units on the one hand and a reservoir for additional empty and filled trays on the other hand.
