Abstract: A device for securing and/or registering the stencil frame for a screen printing machine, said screen printing machine having amongst other things a printing table and a scraper and/or ink application device arranged above the printing table. Between the printing table and the scraper arrangement are arranged one or more guides (6, 7) intended to interact with the stencil frame (5). These guides are designed in such a way that the stencil frame (5) is able to be moved or displaced as a single unit from an initial position outside the screen printing machine to an appropriate position inside the screen printing machine, and vice versa. Inside the screen printing machine are present registering devices (8, 9) intended to guide the stencil frame into a registration position. The elements intended to interact with the stencil frame comprise at least two guides (6, 7) running parallel to each other, along which the stencil frame (5) is capable of being displaced.

Abstract: An arrangement for feeding a stencil frame having a stencil mounted therein to a silk screen printing machine and/or for discharging a stencil frame therefrom, in which the silk screen printing machine is provided with means for receiving a stencil frame and means for holding the stencil frame firmly in the printing machine. One or more stencil frame magazines are arranged between the printing machine a transfer and arrangement for feeding a stencil frame to the magazine and/or receiving a stencil frame therefrom.Each magazine is allocated horizontal planes for each of which there is provided means adapted to feed a stencil frame to the printing machine and/or adapted to remove a stencil frame from the printing machine.

Abstract: The invention relates to a method and apparatus for sawing logs having a curved longitudinal length to obtain maximum recovery of sawed planks therefrom. There are provided several sawing stations for handling the curved log including edge sawing, heart split sawing along the curved center line of the log and perpendicular to the edge sawed surfaces to produce two sections having curved center cut surfaces, and dividing sawing each section parallel to the center cut surface.

Abstract: A printing machine having a reciprocatingly movable printing table, preferably of the type having a stencil and a squeegee associated therewith is disclosed. Said squeegee being intended, in a printing position for the material, to press printing ink through the stencil to a rigid material arranged beneath the stencil. Said printing table is movable between a first position, i.e. a material insertion position, and a second position, i.e. a material printing position, and said printing table exhibiting one or more fixed registering means arranged to co-act with corresponding registering means in said material to position said material relative to said printing table in the material insertion position of said table, subsequent to the material occupying the printing position and print being applied to said material. The registering means are activated between the printing table and devices releasing said material.

Abstract: Apparatus for sawing of curved-form timber feeds the log past a band saw such that the cut follows the curved form of the log. Spaced guides function to guide the log in a curved-form path through the saw. The guides are displaceable in a direction transversely to the feeding direction of the log depending on the curved form of the log. The guides may comprise guide rollers provided on each side of the log to be forced to the sides of the log.
