An apparatus (1) for controlled motion of one or more printing units (2) designed for printing images (I) on one or more faces (F) of a sheet material (M) that is designed to move in a feeding direction defining a longitudinal axis (L). The apparatus (1) is adapted to be associated with a machine (3) for cutting and creasing customized packages and comprises a stationary frame (10) defining an elongate transverse axis (T), at least one box-like support (12) for a corresponding printing unit (2), which is slidably mounted on transverse guide means (13) integral with the frame (10), drive means (26) for driving the box-like support (12) along transverse guide means (13), the drive means (26) comprise at least one section of a stationary and flexible belt (27) having a predetermined length (I) and end portions (28, 29) stably secured to the frame (10), as well as at least one powered roller (31) associated with the support (12), and having an intermediate portion (30) of the belt section (27) at least partially wound thereon for its rotation to promote the movement of the support (12) relative to the belt section (27). A machine (3) for cutting and creasing customized packages, comprising the apparatus for driving the printing units (2).

There is provided an inkjet recording apparatus including: a plurality of ink ejectors each having a nozzle array in which two or more nozzles each of which ejects ink are one-dimensionally arranged; a support member to which the plurality of ink ejectors are attached at positions different from one another in a predetermined arrangement direction in a state where the nozzle array is oriented in the arrangement direction; and a support member deformer that deforms the support member in a direction in which a deflection of the support member is reduced.

A stay rod includes a guide to slidably hold a functional part, the guide to be fixed to an apparatus body, a plurality of first parts each including a guide surface to form the guide, and a plurality of second parts each including a mounting surface to be mounted to the apparatus body. The plurality of first parts and the plurality of second parts are combined to have an elongated box-shaped cross section in which the guide surface of the plurality of first parts faces the mounting surface of the plurality of second parts, the plurality of first parts is arranged side by side in a longitudinal direction of the stay rod and is joined to the plurality of second pars at each joint formed at each end of the plurality of first parts.

A printer mechanism having multiple hosts on a common platform, the printer mechanism comprising: a conveying platform (100) used for conveying a printing substrate, and an inkjet system (200) composed of a number of relatively independent hosts (210) connected to each other, the host (210) comprising at least a main cabinet (211) and an upper cabinet (212) extending from a side of the main cabinet (211), and the upper cabinets (212) of the whole inkjet system (200) being distributed in parallel above the conveying platform (100); and the printer mechanism further comprising a spray carriage system (300) composed of a number of relatively independent spray carriages (310) installed with a spray nozzle module and connected to each other, the spray carriage system (300) being disposed between the inkjet system (200) and the conveying platform (100), and the spray carriages (310) being correspondingly connected to the hosts (210) one by one.

An oval printing machine includes a guide, defining a closed path (P); one or more supports, movable on the guide, the one or more supports being adapted to support items to be printed; one or more operating stations positioned along the path (P) for processing the items to be printed; at least one digital printing station positioned along the path (P), for printing the items supported by the one or more supports. The digital printing station includes a structure substantially integral with the guide, and a first printing element associated with the structure and movable relative to the structure. The printing element is movable in a first direction (D1) that is transversal to a second direction (D2) in which the guide extends at the digital printing station.
