In order that the frictional resistance between cleaning cloth and the surface of a roller is reduced even if the cleaning cloth is in contact with the surface of the roller, a roller cleaning device (1) is formed by mounting a supply means (3), a winding means (4), and a pressing body (7) on a cleaning unit (2) capable of moving in the direction of the axis of the roller (6). The pressing body (7) is disposed between the supply means (3) and the winding means (4) and is pressed toward the surface of the roller (6) while being tilted in the direction in which the pressing body (7) moves away from a change on the surface of the roller. The cleaning cloth (5) is linearly pressed against the surface of the roller (6) so as to be in contact with the surface. The width of the cleaning cloth (5) is set to be less than the length of the roller (6).

A cover is applied to the cleaning cloth roll in a state in which cleaning cloths impregnated with a cleaning solution are wound around a core, thus realizing a cleaning cloth roll in which the cleaning solution does not seep into the core. In the disclosed cleaning cloth roll (1) to which a cover (2) is applied in a state in which cleaning cloths (3) impregnated with a cleaning solution are wound around a core (4), an anti-seepage treated area in which cleaning liquid does not seep into the core is created on the surfaces (7, 8) of the core. By this means, the amount of cleaning solution in the cleaning cloths is stable even when the cleaning cloth roll is stored over a long period, and because the dimensions of the core and the strength of the core do not change, the cleaning cloths can be stably unwound from the cleaning cloth roll.

The optimum amount of dampening water to be supplied in an offset printing machine varies in accordance with the constituents of water before it is used for preparation of the dampening water. The present invention provides a dampening water feeder that can maintain the optimum amount of dampening water to be supplied even when the constituents of the water before it is used for preparation of the dampening water vary. The constituents included in water supplied from a water supply unit (1) are changed at a water quality processing unit (5), and dampening water is supplied from a dampening water supply unit (19) to a printing machine through a by-pass route (10) for by-passing the water quality processing unit (5) and a dampening water preparing unit (11) at which the dampening water is prepared by mixing etching solution and the water at a predetermined ratio. A dampening water control unit (24) changes the amount of the dampening water to be supplied from the dampening water supply unit (19) to the printing machine on the basis of whether the water is supplied to the dampening water preparing unit (11) via the water quality processing unit (5) or via the by-pass route (10).

In order to clean two or more cylinders by one cylinder cleaning device, two or more cleaning pads are provided, and the respective cleaning pads are independently operated so that the cleaning cloth is effectively used and waste is reduced. A cleaning cloth (5) is unreeled from a cleaning cloth supply means (6), passes through a first cleaning pad (3) which cleans a first cylinder (1), subsequently passes through a second cleaning pad (4) which cleans a second cylinder (2), and thereafter, is wound by a cleaning cloth winding means (7). A control means (12) retains the cleaning cloth usage state corresponding to the first cleaning pad, and controls a first pad driving means (9), a second pad driving means (10), and a cleaning cloth driving means (11), so that a portion of the cleaning cloth which has been used for the first cleaning pad is not used for the second cleaning pad.

Disclosed is a spray dampener wherein mist of dampening water in the housing is prevented from leaking to the outside of the housing, and intrusion of foreign matter such as ink mist from the outside of the housing into the inside is prevented.  In a housing (6) which opens toward a dampening water roller, spray nozzles (5) for spraying dampening  water to the dampening water roller (1) are housed while being juxtaposed in the longitudinal direction of the dampening water roller (1), an upstream side partition (18) and a downstream side partition (19) each having an opening (24) facing the surface of the dampening  water roller are provided at the upstream end and the downstream end of the opening of the housing, and the partitions are provided, respectively, with drain holes (22, 23) leading to the interior of the housing.  Since the partition captures and liquefies mist effectively, circulation of mist on the inside and outside of the housing can be minimized effectively.

An auto-reject device, which is loaded on a high speed operation sheeter attached to a printing machine such as a web press and extracts a reject sheet by advancing it to a direction different from sheet discharge. A conversion part (7) holding a tip of a continuous sheet (2), which becomes the reject sheet, from the continuous sheet (2) that is cut by a cutting part (4) by a reject signal and advancing the sheet to the direction different from regular sheet discharge is arranged. The continuous sheet (2) transferred from the conversion part (7) is cut by the cutting part (4), is transferred to a belt conveyance part (8) as the reject sheet (2B) and the reject sheet (2B) transferred via a deceleration conveyance part (9) is stored in a reject sheet storage box (13). Since a part of the defective print sheet can precisely be taken out from print sheets which are continuously discharged in the sheeter attached to the web printer of a high speed operation, a holding rate of the good sheet can remarkably be improved, and complication with discharge work of the defective print sheet can also remarkably be dissolved. Since the good sheet for an inspection sheet can precisely be extracted, counting management can precisely be performed.
