Provided are an electrolytic cathode structure that can suppress the degradation of an activated cathode even if a reverse current flows upon the stoppage of operation of an electrolyzer in an electrode structure allowing the distance between the electrode and an electrode current collector to be maintained at an approximately constant value, and an electrolyzer using the same. The electrolytic cathode structure includes a metal elastic cushion member 1 compressed and accommodated between an activated cathode 2 and a cathode current collector 3. At least a surface layer of the cathode current collector 3 consumes a larger oxidation current per unit area than the activated cathode. The electrolyzer is partitioned by an ion exchange membrane into an anode chamber for accommodating an anode and a cathode chamber for accommodating a cathode. The electrolytic cathode structure is used for the cathode.

The invention relates to a splicer device comprising a first unwinding device to unwind a non-endless first material web and a second unwinding device to unwind a non-endless second material web as well as a joining device for joining together the non-endless material webs to form an endless material web. The splicer device further has a storage carriage, which comprises at least one deflection roller to deflect the endless material web and is displaceable between two end positions to form or loosen material web loops of the endless material web. The at least one deflection roller has a respective central longitudinal axis and is tiltable between two tilt end positions to influence a running direction of the endless material web. The splicer device further has an information processing unit to cause tilting of the at least one deflection roller depending on positional information regarding the endless material web and/or another endless material web to be joined thereto.

The invention relates to a sheet depositing arrangement. The sheet depositing arrangement comprises at least one sheet depositing apparatus having a sheet stacking chamber for creating a sheet stack, and a sheet extraction device which in turn has a sheet transporting means that is drivable in a direction of circulation, a sheet delivery region for delivering the sheets to be stacked to the sheet stacking chamber, a sheet stacking region, provided downstream of the sheet delivery region, for stacking the sheets to be stacked into the sheet stacking chamber, and a return region, provided downstream of the sheet stacking region. Furthermore, the sheet depositing apparatus has a sheet retaining device with at least one sheet retaining element, arranged adjacent to the sheet stacking region, for preventing at least one sheet to be stacked from being drawn into the sheet extraction device from the sheet stacking chamber by the sheet transporting means.

Disclosed is a corrugated paperboard box making machine which comprises a feeding control mode setting unit for setting a feeding control mode to one of a first feeding control mode for controlling a sheet feeding apparatus and a second feeding control mode for controlling the sheet feeding apparatus such that the sheet feeding operation is performed plural times during the period of time in which the printing rotor is rotated 360 degrees, and a control apparatus for controlling the sheet feeding apparatus according to the set feeding control mode. The control apparatus is operable to execute a sheet feeding stop control processing of, when the second feeding control mode is set, controlling the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

The invention relates to a splicer assembly for splicing material webs. The splicer assembly comprises a first dispensing device for dispensing a finite first material web, a second dispensing device for dispensing a finite second material web, a connecting device for connecting the finite first material web and the finite second material web so as to form an endless material web, and a material web threading assistance assembly for assisted threading of the finite first material web or of the finite second material web into the splicer assembly in a threading procedure. The material web threading assistance device comprises at least one conveying installation for conveying the finite material web to be threaded in a threading direction in the threading procedure, and a conveying installation drive installation for driving the at least one conveying installation in the threading procedure.

A conveyor includes a first conveyor deck having a first plurality of contact elements, each having a contact surface movable around a closed path from a contact region to a non-contact region, the first contact regions lying in a plane or being bounded by the plane and a second conveyor deck having a second plurality of contact elements, each having a contact surface movable around a closed path from a contact region to a non-contact region, these contact regions lying in a second plane or being bounded by the second plane.
