A printing control apparatus configured to control a binding unit configured to perform a binding processing for binding sheets without using a staple includes a control unit that controls the biding unit to divide sheets subjected to printing into sheet groups in units of a number of sheets bindable by the binding unit, and to apply the binding processing to each of sheet groups or controls another binding unit to bind the sheets subjected to printing using a staple.

A sheet processing apparatus includes a conveyance unit, a punch member configured to be rotatably supported and punch a hole at a predetermined position, a sensor, a driving source configured to rotatably drive the punch member, and a control unit configured to control the driving source. The control unit is configured to (1) control the driving source based on a punching gap distance between a last punching position of a preceding sheet and a first punching position of a succeeding sheet in the sheet conveyance direction, and a rotational position of the punch member, and (2) perform an avoidance process of avoiding a punching process of punching the hole in the succeeding sheet in a case where the control unit judges not to perform the punching process in the succeeding sheet when the succeeding sheet has reached the detection position.

In a reel-up for reeling of fiber webs, a web travelling in direction (S) is cut by two water jet nozzles moving in a transverse direction. Two cuts (C1, C2) are formed by the nozzles starting from the web edges moving to the web center where the cuts (C1, C2) cross or meet forming a V-shaped tail end (V1). After the cuts nozzle movement is stopped and after the return of the nozzles, cutting is restarted from the center toward the edges so the web W is cut by two cuts (C3, C4) forming a substantially V-shaped beginning end (V2) and between the cuts (C1, C2) for the tail end (V1) and the cuts (C3, C4) for the beginning end (V2) there is formed one web reject part (R) with two substantially V-shaped cuts. Cross-direction travel distance (L1, L2) of each nozzle is substantially shorter than the web width.

A suction fan of a sheet feeder sucks in air through a sheet feeding belt to generate flotation air. The suction fan uses the flotation air to attract set sheets by suction. A belt motor rotates a sheet feeding belt and feeds out a sheet of the set sheets. An interval measurer measures a sheet-to-sheet interval when the suction fan is attracting the sheet by suction. Based on an output of the interval measurer, a controller recognizes the sheet-to-sheet interval. Based on the recognized sheet-to-sheet interval, the controller adjusts a flow rate of the flotation air.

In a turn-up method for a reel-up for reeling of fiber webs, a web travelling in direction (S) is cut by two water jet nozzles moving in a transverse direction in relation to the web travelling direction (S). Two cuts (C1, C2) are formed by two water jet nozzles starting from the edges of the web (W) and moving to the web center where the cuts (C1, C2) cross or meet forming a V-shaped tail end (V1). After the cuts the movement of the water jet nozzles is stopped and after the return movement of the water jet nozzles, cutting is started again from the center toward the edges so that the web W is cut by two cuts (C3, C4) and a substantially V-shaped beginning end (V2) to the web W is formed and between the cuts (C1, C2) for the tail end (V1) and the cuts (C3, C4) for the beginning end (V2) there is formed one web reject part (R) with two substantially V-shaped cuts. A turn-up device for a reel-up for reeling of fiber webs has two water jet nozzles, in which the cutting by the water jet nozzles (10,12) may be stopped between cutting of a tail end (V1) and cutting of a beginning end (V2) for a selected time for forming only, wherein there is one reject part (R) in the turn-up and the cross-direction travel distance (L1, L2) of each nozzle is substantially shorter than the width (L) of the web (W).

Provided is a sensor control apparatus including a main board and a first sensor to a third sensor that are connected in series to the main board. The main board operates the first sensor to the third sensor based on a normal operation mode of operating all the first sensor to the third sensor and a power reduction mode of operating only the first sensor. In the first sensor to the third sensor, the first sensor that operates in the power reduction mode is arranged on an upstream side of the second sensor and the third sensor that do not operate in the power reduction mode, the upstream side being set to a side on which the main board is provided. With such a configuration, the sensor control apparatus can suppress power consumption by operating only a required sensor at a time of the power reduction mode.
