Methods and apparatus, including computer program products, are described for forming individual packages in a food packaging machine (100) comprising a plurality of sub-systems. One or more local variable values (142) are received, which indicate measurements by the food packaging machine (100) of one or more physical parameters for a local sub-system (120). One or more remote variable values (204) are received, which indicate measurements by the food packaging machine (100) of one or more physical parameters for one or remote sub-systems. One or more control parameter values are determined for the local sub-system (120) of the food packaging machine (100), by processing the remote variable values (204) and the local variable values (142) using a reinforcement learning model (206) and a local control model (210). One or more control parameters of the local sub-system (120) are adjusted in accordance with the determined control parameter values. The formation of individual packages (122) by the food packaging machine (100) is controlled in accordance with the adjusted one or more control parameters.

A tape supply device that supplies a tape to an optical cable, the tape supply device includes: an accumulator unit of a multistage unit type divided into units, each of the units including a plurality of movable rollers and a plurality of fixed rollers, the units being connected in series; and a control unit configured to control a supply order of the tape from the units.

A packaging machine may include a foil transport device and a controlling system for controlling an operation of at least one drive unit of the foil transport device. The controlling system is designed to activate the drive unit during a production run of the packaging machine on the basis of a speed- and/or temperature-dependent friction moment characteristic curve detected by means of a rotationally driven measurement run carried out by the drive unit. The disclosure furthermore relates to a method for controlling a drive unit of a foil transport device.

A method for the monitoring and control of the operating conditions of a fiber web machine or paper finishing machine, where the monitoring and control are performed on a rotatable machine element (41) equipped with a sensor assembly (24) that measures temperature, and generates a measurement signal (25), and a cross-directional temperature profile (21) of the machine element is generated from the measurement signal. One or more reference profiles (35) are generated for the cross-directional temperature profile of the machine element. The cross-directional temperature profile of the machine element generated from the measurement signal and at least one reference profile generated for it are compared to find a change concerning the operating conditions of the fiber web machine or paper finishing machine, and actions are performed on the basis of said change. The invention also relates to a corresponding system, a rotating machine element and a computer program product.

A manufacturing method for a glass roll includes cutting a glass ribbon along a longitudinal direction thereof in a cutting region on a conveyance path while conveying the glass ribbon, and taking up the cut glass ribbon around a roll core at a downstream end of the conveyance path. A conveyance-mode changeable region is provided between the cutting region and the downstream end of the conveyance path. The conveyance-mode changeable region enables a change in conveyance mode between a first mode of conveying the glass ribbon in a tensioned state and a second mode of conveying the glass ribbon in a loosened state. After the leading end portion of the glass ribbon is wound around the roll core in the first conveyance mode, the conveyance mode is shifted from the first conveyance mode to the second conveyance mode.
