The sign fixing system consists of a flat shaped piece of thin metal plate (12) which has various holes and a slot cut into it. The edges (20-24) are bolted to the bent over edges (14) of triangular, circular square etc. signs. The slots and/or holes in the face of the metal ...
A plate as a support element for a spindle frame is a substantially flat plate 3 formed into one piece from metal material by a single pressing or blanking operation. Said single pressing operation also forms in the plate surface lightening apertures, passage holes, and fixing holes for operatio...
