A printed unit block aligning device includes a supporting element and an alignment transfer rail. The supporting element is opened and closed between a supporting position and a releasing position. The alignment transfer rail receives the group of the printed unit blocks dropped in response to move of the supporting element to the releasing position, aligns the printed unit blocks in each line unit block in a vertical direction, and feeds the printed unit blocks vertically at a constant speed using alignment transferring element. An electrical controlling element is provided that electrically controls timing of dropping the printed unit blocks from the supporting element onto the alignment transfer rail. While a speed of transfer of the horizontal feeding and transferring element are uniform for any imposition structure, the electrical controlling element controls timing of dropping the printed unit blocks in a manner that depends on the numbers of layers in each vertical line in different imposition structures.

An arrangement in a warehouse and a method for forming narrow rolls are disclosed. The narrow rolls are formed from a jumbo reel. At least two slitting machines are used for forming the narrow rolls. The jumbo reel has an axial direction when positioned on the slitting machine. The narrow rolls are transferred to the warehouse in the axial direction. The at least two slitting machines are positioned overlapping.

A slit device including a first transport section which transports a web in a transport direction while nipping the web, a second transport section which is disposed in parallel with a direction intersecting the transport direction of the first transport section and which transports the web in the transport direction while nipping the web, and a cutting section which is disposed between the first transport section and the second transport section in a direction intersecting the transport direction and which cuts the web along the transport direction, in which a cutting position at which the web is cut by the cutting section is a position within a nipping area where the first transport section nips the web along the transport direction, or is a position downstream of the nipping area in the transport direction.

This disclosure describes techniques for automatically controlling the operation of a slitter (40) to convert a web (20) of material into smaller slit rolls (64, 66, 68). A slitter director (60) may automatically control the operation of a slitter (40) for defect removal, web splicing, and/or slit roll rejection based on continually registering previously-generated anomaly data (62) with physical locations of the web (20).
