A lightweight interchangeable magnetic sleeve and method of manufacture thereof are disclosed. The sleeve assembly comprises an annular tube in the exterior surface having recesses filled with comparatively rigid magnetic means which are firmly adhered therein. The sleeve assembly includes a tubular radially compressible liner component, relatively slightly shorter than the tube, and bonded inside and substantially axially centrally within the tube thus leaving interior cylindrical end regions of the tube exposed beyond the annular end surfaces of said liner. The remaining exposed interior cylindrical surfaces of the tube are rebated back from the liner exposing annular shoulders within the tube. The rebates are tapped so that correspondingly sized threaded end rings of a more structurally robust, rigid and resilient material than the tube material, can be fitted into the tube ends and tightened against the annular shoulders created by the rebating, placing the entire sleeve assembly under slight compression.

A transfer device and a coating machine are disclosed. The transfer device includes a transfer plate and a printing roller. A projection is formed on a first surface of the transfer plate; a first recess corresponding to the projection is formed on the printing roller; and when the transfer plate covers a surface of the printing roller, the projection and the first recess are matched with each other to fix the transfer plate with the printing roller. The transfer plate in the transfer device will not be subjected to extended deformation and sliding even under an action of external force during printing process, so that the production quality can be maximally guaranteed.

A method of stenciling a stenciled graphic in a desired position and orientation on the graphic-display surface of a substrate includes providing at least one stencil template defining the stenciled graphic and at least one guide element including mutually-space template positioning indicia. Both the stencil template and the guide element are magnetically attracted to the substrate. The guide element is magnetically affixed to the graphic display surface in a desired location and orientation. The stencil template is magnetically affixed to the graphic-display surface in a location selected with positioning reference to at least one template-positioning indicium of the guide element. With or without the guide element still affixed, pigment is applied to the graphic-display surface through the at least one stencil template to impart to the graphic-display surface the desired stenciled graphic. The at least one stencil template is then removed from the graphic-display surface.

The object of the invention is a magnetic cylinder, in particular for a device for printing, having a cylindrical body and two bearers mounted at the ends of the body, wherein at least one bearer includes a cylindrical flange adjacent to the body, wherein a plurality of magnetic channels are formed in the body extending substantially parallel to the longitudinal axis of the body, radially spaced from the longitudinal axis of the body, wherein corresponding magnetic assemblies are inserted into the magnetic channels. The object of the invention is also a method for producing the magnetic cylinder.
