  • Patent number: 4862686
    Abstract: A lightweight, rigidified support stand for textile spinning and like machines may be easily manufactured with close tolerances without resort to a casting process by welding together a profiled sheet metal base having a substantially flat main support surface provided with a plurality of receptacles for fastening of machines components and a sheet metal brace member of a U-shaped profile. The formation of the fastener receptacles in the base member enables the receptacles to be arranged in a single plane with close tolerances, while the brace member serves to rigidify the base member.
