Abstract:
A printing machine comprising:a rotatable impression cylinder which has a plurality of effective surfaces for holding a sheet-like material along a peripheral direction at a predetermined interval;a first printing portion which is oppositely brought into contact with said impression cylinder and applies a printing to said sheet-like material;a second printing portion which is oppositely brought into contact with said impression cylinder in a downstream side in a rotational direction of said impression cylinder with respect to an oppositely contacting position of said first printing portion with said impression cylinder and applies a printing to said sheet-like material;a number printing portion which is oppositely brought into contact with said impression cylinder in a downstream side in the rotational direction of said impression cylinder with respect to an oppositely contacting position of said second printing portion with said impression cylinder and applies a number printing to said sheet-like material; anda transfer cylinder which is oppositely brought into contact with said impression cylinder in a downstream side in a rotational direction of said impression cylinder with respect to an oppositely contacting position of said number printing portion with said impression cylinder and receives said sheet-like material from said impression cylinder,wherein said first printing portion, said second printing portion, said number printing portion and said transfer cylinder are respectively arranged so that a transfer distance of said sheet-like material which is defined by said impression cylinder between the oppositely contacting position between said first printing portion and said impression cylinder and the oppositely contacting position between said second printing portion and said impression cylinder has a length equal to or more than a length in a transfer direction of a printing surface of said sheet-like material, and a transfer distance of said sheet-like material which is performed by said impression cylinder between the oppositely contacting position between said number printing portion and said impression cylinder and an oppositely contacting position between said transfer cylinder and said impression cylinder has a length equal to or more than the length in a transfer direction of an printing surface of said sheet-like material and a transfer distance of a sheet-like material which is performed by said impression cylinder between the oppositely contacting position between said first printing portion and said impression cylinder and the oppositely contacting position between said number printing portion and said impression cylinder has a length equal to or less than a length obtained by adding twice a length between adjacent effective surfaces of said impression cylinder to a length of said effective surface.
