Definitions

  • a winding machine for winding sheet metal strip has at least one chain of rollers, interconnected by links, which can be moved into a position partly surrounding [30] Forelgn Apphcatlon Pnonty Data a spindle to form a guide for the leading edge of a Apr. 17, 1973 Italy 23096/73 Sheet meta] strip to be wound on the spindle.
  • the chain is protidCl.f 1 5 0 34 277 8 vided with an end link including a roller which can be 1e 0 care pivoted into an operating position where it forms an extension of the roller chain to accommodate the larger of the two spindles, or away from the operating position to a position where it does not interfere with a winding operation on a smaller spindle.
  • This invention relates to a winding machine for making coils of sheet metal strip, of the type consisting of a rotatable winding spindle supported on a horizontal axis by a bearing structure, means for conveying the sheet metal strip towards the said spindle, a slide movable in a direction transverse to the axis of the said spindle, between a rest position spaced from the said spindle and a working position close to the said spindle, at least one chain of rotatable rollers positioned to one side of the said spindle with the axes of the rollers extending parallel to the axis of the said spindle, at least two jaw-like arms pivoted at one of their ends to the said slide (the pivot axes of the arms being parallel to the axis of the spindle), and supporting, at their other ends, respective end rollers of the said roller
  • Winding apparatus at present in use consists essentially of a rotatably mounted winding spindle, located with its axis horizontal, carried by a bearing structure, and an endless belt which passes over rollers, which may be driven rollers, and which also passes over a part of the surface of the said spindle.
  • a metal strip to be wound upon the spindle is fed to the apparatus in such a way that it passes between the spindle and the belt; the belt presses the plate against the spindle, strain relieving and bending it at the same time and thereby causing the required formation of the first turns of the coil.
  • the length of the roller chain, (or the belt, in the case of the prior art winding appliances) should be such that the chain (or the belt) extends around not less than three quarters of the whole outside of the said spindle when the apparatus is in operation.
