A pleated filter preparation system is provided for accurately counting pleats along a continuous sheet of pleated filter material and cutting the sheet into filter strips to be formed into filters. The pleated filter preparation system includes a pleat driver having multiple drive gears that engage with the pleats of the pleated filter material to move the pleated filter material through the system. A pleat counter counts peaks and valleys of each pleat comprising the pleated filter material so as to identify a target pleat to be cut. The pleat counter clamps and stretches the target pleat to distinguish the target pleat among the other pleats. A punch cut station cuts the target pleat to form a filter strip having a desired number of pleats. A pleat compressor compresses the filter strips to a predetermined size and then ejects the filter strips into a suitable container or bin.

A belt replacement device may include: a base portion having a belt placed thereon, the belt being wound in a roll shape; a rotating portion mounted on the base portion, and rotating the belt wound in a roll shape; a transporting portion holding and transporting the belt passed through the rotating portion; a guide portion guiding the belt discharged through the transporting portion; and a loading portion to which the belt dropped from the guide portion is loaded, and the belt replacement device can improve winding workability for the belt.

An apparatus and method for forming zig-zag folded logs of web material is provided. The apparatus and method allows for forming logs having different sheet lengths on a same machine. Logs of web material having weakened regions at different locations between folds in the zig-zag folded web are also provided.

A method for stacking a ply (50) which is transferred from a rubber mixing system to a stacking system (100) comprises the steps of transferring the ply (50) to a stacking head (120) of the stacking system (100); passing the ply (50) to a motorized belt (110) of the stacking system (100), the motorized belt (110) being able to turn in both directions and being able to move in translation, and the motorized belt (110) being situated between the stacking head and a pallet (P) chosen from a pallet (P) with edges and a pallet (Q) without edges; and setting the motorized belt (110) into movement in translation so as to move along a path such that the motorized belt (110) receives the ply (50) from the stacking head (120) and makes a downstream end (50b) of the ply (50) to be stacked accessible in order to connect it to an upstream end (52a) of a ply (52) of a successive pallet and form a butt joint between the plies (50, 52).

In a method for packing a spacecraft membrane (1) which in a plane of extension comprises a longitudinal axis between opposite longitudinal corners (4) and a transverse axis running transverse to the longitudinal axis and through transverse corners into a spacecraft membrane package, two packing steps are executed: In a first packing step, the spacecraft membrane (1) is packed into a transverse package (9) along the transverse axis. In a second packing step, the transverse package (9) is packed into a longitudinal package along a longitudinal axis. The packing of the spacecraft membrane (1) in the first packing step comprises a packing of material of the spacecraft membrane (1) from or on both sides of the longitudinal axis. In the first packing step, the spacecraft membrane (1) is packed in such a way that in the created transverse package (9) the transverse corners are freely accessible. In the second packing step, the transverse package (9) is packed in such a way that in the created longitudinal package the longitudinal corners (4) are freely accessible. The longitudinal package is unpacked by pulling on the longitudinal corners (4). Subsequently, the transverse package (9) is unpacked by pulling on the transverse corners.
