摘要:
The present invention concerns the field of supports for canvases and in particular a framework that can be made by an end user alone (directly, like a painter, artist or other, or indirectly, like for example a craftsman or a retailer in general).
摘要:
A support system for and method of supporting a printing screen unit (103) in a screen printing machine. In one aspect the support system includes a support assembly (115) comprising: a support unit (117) for supporting the printing screen unit, the printing screen unit comprising a printing screen (105) including printing apertures (106) through which printing medium is printed onto a workpiece (W); and a clamping mechanism (121a,121b) for clamping the printing screen; and a control unit (116) for controlling operation of the support assembly, wherein the control unit is configured to operate the clamping mechanism to clamp the printing screen in a printing phase in printing printing medium onto the workpiece so as to fix the lateral, in-plane position of the printing screen, and release the printing screen in a separation phase in separating the printing screen and the workpiece.

A fixing frame (1) and an assembled fixing device printing solder paste on a printed circuit board improve an assembly process, cut production costs, and save storage space. The fixing frame (1) has a plurality of fixing portions (11) and a motor unit (13). The fixing portions (11) are connected to each other to define a hollowed-out planar region (12). The motor unit (13) generates a plurality of pulling forces by means of mechanical transmission. The assembled fixing device includes a fixing frame (1) and a stencil (2). The stencil (2) has a solder paste printing region (21) and a plurality of fixing regions (22). The edge of the solder paste printing region (21) extends outward to define the fixing regions (22). The fixing regions are movably fixed to the fixing portions (11) and bear the pulling forces. The solder paste printing region (21) lies within the hollowed-out planar region (12). The directions of the pulling forces are coplanar with the solder paste printing region (21).

摘要:
An extension tool of a sheet-shaped material comprising, in order to stretch a sheet-shaped material over its entirety at minimum adjusting portions and with a uniform tension, four corner members disposed at locations corresponding to the four corners of a rectangle, four frames disposed at locations corresponding to the sides of the rectangle and supported at the opposite ends thereof by the corner members so as to be movable in the directions of the sides, and four rods disposed so as to pass through the four frames respectively. One set of corner members located on the diagonals of the rectangle are respectively provided with moving mechanism for moving the rods along the sides of the rectangle. The extension tool of a sheet-shaped material further comprises a transmission mechanism for converting the moving of a rod on a side of the rectangle in a direction from one corner member toward the other corner member making a pair with the one corner member (or its reverse direction) into the moving of the other rod stretching from the other corner member in a direction away from the other corner member (or approaching direction).
摘要:
In consists of an angular element (1) having level surfaces (2, 3) of interface between the angular elements and the beams. Said level surfaces (2, 3) are angulated in such a way to form an angle (4) different to the right angle and with a transversal stiffener (5) so to permit the maintenance of the angulations of the surfaces (2, 3) under loading. Onto said surfaces holes (6) are present to permit the passing of fixing elements (7) to the beams (8) and to inside holes (9) of the same beams corresponding to the holes (6) and to obtain at the assembling a closed structure (10) with arched beams (8) having concavity inward of the structure.
