Abstract
In a method and apparatus for printing on objects using a screen printing procedure, the print image applied to a respective object is dried by UV-rays produced by at least one UV-radiating device. Drying of the applied print image is effected during a transportation movement which the object performs in order to be transported after the drying operation from one location to another. The radiating device which produces the UV-rays is moved with the object at least during a pert of the transportation movement in the direction of movement of the object, in such a way that in such movement the print image is dried.
Claims23
Apparatus for priming on an object and drying the object with a UV-radiating device comprising:
- (a) at least one printing station including at least one screen printing stencil and a doctor cooperating therewith for priming images on an object in a printing operation;
- (b) at least one transportation device for assisting in transporting the object through at least a portion of the apparatus;
- (c) at least one UV-radiating device for delivering UV-rays in a region to an object for drying in a drying operation at least one prim image applied thereto by the screen priming stencil and the doctor;
- (d) means disposing the UV-radiating device movably so that the UV-radiating device is movable in a direction of movement of the printed object during a transportation movement of the printed object, and so that during the transportation movement of the printed object at least the part of the object which bears the applied print image is passed in the region of the UV-rays;
- (e) a first holding means for carrying the UV-radiating device;
- (f) a third holding means comprising holders for carrying the screen printing stencil;
- and
- (g) means operatively connecting the first holding means to the third holding means, thereby causing the first and third holding means to move in unison.
Apparatus for priming on an object and drying the object with a UV-radiating device comprising;
- (a) at least one priming station including at least one screen printing stencil and a doctor cooperating therewith for printing images on an object in a printing operation;
- (b) at least one transportation device for assisting in transporting the object through at least a portion of the apparatus;
- (c) at least one UV-radiating device for delivering UV-rays in a region to an object for drying in a drying operation at least one print image applied thereto by the screen printing stencil and the doctor;
- (d) means disposing the UV-radiating device movably so that the UV-radiating device is movable in a direction of movement of the printed object during a transportation movement of the printed object, and so that during the transportation movement of the printed object at least the part of the object which bears the applied print image is passed in the region of the UV-rays;
- (e) a first holding means for carrying the UV-radiating device;
- (f) a second holding means comprising holders for carrying the object at least during the drying operation;
- and
- (g) a third holding means for carrying the screen printing stencil;
- and
- (h) means operatively connecting the first holding means, the second holding means, and third holding, means thereby causing the first, second and third holding means to move in unison.
A method of priming on an object using at least one screen printing stencil and a doctor cooperating therewith and drying the object with at least one UV-radiating device, the UV-radiating device and the object disposed in first and second holding means, respectively, which are operatively connected together so that they move in unison, the drying being performed while the object passes through a drying area with the assistance of a transportation device, the method comprising the steps of
- (a) applying a printed image to the object in at least one printing station containing the screen printing stencil and cooperating doctor;
- (b) delivering the printed object to a drying station containing the UV-radiating device;
- and
- (c) drying the image applied on the printed object by passing at least a part of the object in a region of UV-rays produced by the UV-radiating device during a transportation movement of the printed object through a treatment area, while also simultaneously moving a preceding object through the printing station, the operative connection of the first and second holding means allowing the UV-radiating device and the object to move in unison to simultaneously dry the printed object while the preceding object is printed.
A method of printing on an object comprising the steps of:
- providing at least one screen printing stencil and a doctor cooperating therewith;
- providing at least one UV-radiating device;
- disposing the UV-radiating device and the screen printing stencil in first and third holding means, respectively;
- operatively connecting the first and third holding means so that they move in unison;
- applying a printed image to the object in at least one printing station containing the screen priming stencil and cooperating doctor;
- delivering the primed object to a drying station containing the UV-radiating device;
- drying the image applied on the printed object by passing at least a part of the object through a region of UV-rays produced by the UV-radiating device during a transportation movement of the printed object through a treatment area;
- and
- moving simultaneously with the transportation movement of the printed object a preceding object through the printing station, the operative connection of the first and third holding means causing the UV-radiating device to move in unison with the screen printing stencil to simultaneously dry the primed object while the preceding object is printed.
