摘要:
The invention relates to a silk-screen printing machine (2) comprising a frame (4), a plate (6) for transporting the objects (18, 20), which plate (6) is mobile relative to the frame, a first (10) and a second (12) printing station, means (7) for displacing the plate (6) in order to bring the objects (18, 20) into alignment with the printing stations, and an object support (22) capable of carrying a first (18) and a second (20) object.The first printing station (10) is capable of printing solely the first object (18). The second printing station (12) is capable of printing solely the second object (20). The displacement means (7) are suitable for displacing the object support (22) between the first (10) and the second (12) printing station after the first object (18) has been printed at the first printing station (10) and the second object (20) has been printed at the second printing station (12).

A printing machine includes a support stand, a plate rotational with respect to the stand about an axis of rotation, elements for driving the plate in rotation, at least two mandrels for holding two articles to be printed in succession, the mandrels being carried by the plate, elements for driving the mandrels in rotation about axes of rotation parallel to the axis of rotation of the plate, and a plurality of workstations distributed around the rotational plate. The machine includes elements for the displacement of each mandrel in a plane parallel to the plane of the plate, in order to modify the spacing between the axis of rotation of the mandrel and the axis of rotation of the plate. The elements for the displacement of the mandrels are designed to synchronize the displacement of each mandrel with the rotation of the plate.

A silkscreen printer machine (8) includes: a support structure (48); and at least one printing station (54) secured to the structure (48) and including at least one screen support (68) presenting a reception area adapted to receive a screen texture (70) having a pattern for printing placed thereon. The screen support (68) is carried by at least three support elements (78) secured to the structure (48), the support elements (78) not being in alignment and being positioned on either side of the reception area (69). The invention also provides associated printer apparatus.

A printing machine is providing including a transporter for transporting objects to be printed, a printing station including at least four printing units arranged to project ink on the objects to be printed, a transfer device for transferring an object to be printed from the transporter to the printing station and from the printing station to the transporter. The printing station includes a single mandrel corresponding to the maintenance of an object to be printed, the corresponding mandrel being rotatably movable around its axis so that the printing units project ink onto the object maintained by the corresponding mandrel, the printing station being arranged to print only the objects maintained by the corresponding mandrel.

The invention relates to a printing machine, comprising a support stand (2), a plate (4) rotational with respect to the stand (2) about an axis of rotation (A-A), means for driving the plate in rotation, at least two mandrels (6) for holding two articles to be printed in succession, the said mandrels being carried by the plate (4), means (94) for driving the mandrels in rotation about axes of rotation (B-B) parallel to the axis of rotation (A-A) of the plate (4), and a plurality of workstations (18, 18A, 18B) distributed around the rotational plate (4). This machine is characterized in that it comprises means for the displacement of each mandrel in a plane parallel to the plane of the plate (4), in order to modify the spacing between the axis of rotation (B-B) of the mandrel and the axis of rotation (A-A) of the plate, and in that the said means for the displacement of the mandrels are designed to synchronize the displacement of each mandrel (6) with the rotation of the plate (4).

A squeegee head includes a squeegee carried by a squeegee-holder carried by a support and whose inclination on the support is adjustable by rotation about a pivot axis parallel to the lengthwise direction of the squeegee. The squeegee-holder pivot axis is substantially coplanar with the free edge of the squeegee. The squeegee heads finds a specific application in silkscreen printing machines.

A printing assembly for a printing machine comprises a drum mounted for rotary movement about an axis and supporting a plurality of object holders parallel to the drum axis and uniformly circumferentially spaced around the axis. A drum drive imparts continuous rotary movement. A printing station at the periphery of drum for printing successive objects in the course of displacement by the printing station. The printing station is carried by a beam and includes a screen and squeegee. A beam drive is synchronized with the drum drive and imparts arcuate reciprocating movement to the beam about the axis such that the printing station tracks movement of an object at the printing station. The screen is disposed substantially parallel to the axis and mounted for tangential movement to the drum and the object at the printing station. A screen drive imparts rectilinear reciprocating movement to the screen relative to the beam in synchronism with beam movement.

This is a frosting machine of the kind comprising, traversed by a conveyor (14) adapted to drive the articles (10) to be frosted, at least one treatment station (15A) at which said articles (10) are treated with a liquid.According to the invention, and in combination, said treatment station (15A) comprises at least one spray manifold (18) adapted to spray the liquid concerned, and at said treatment station (15A) are operative rotator means (14, 34) adapted to rotate the articles (10) on themselves in the jet of liquid sprayed by said spray ramp (18).Application, in particular, to frosting bottles.
摘要:
A printing machine suitable for printing objects with an oblong or a circular transverse cross-section includes a fixed printing shaft. An object to be printed is rotated about the printing shaft in contact with a flat printing plate or the like carried by a mobile assembly. The distance between the printing shaft and the printing plate or the like is corrected automatically. A drive shaft rotates the object to be printed through a transmission system which provides at least two transmission ratios.
