Definitions

  • the invention relates to a device for creasing continuously conveyed flat workpieces to be folded along crease lines, preferably for attaching the inclined Pre-folding lines on tube pieces to prepare the folds Cross bases to be formed, consisting of parallel to each other Shaft-mounted creasing tools, some of which are made from a Groove (female) and the other part from a web (male) exists that is helical over those described by them Envelope cylinders run and in the contact area of their Surface lines come into engagement with one another, with the Setting the length of the crease or pre-fold lines Tool part from packages of close to each other, the Disc-shaped or plate-shaped segments carrying grooving tools consists of at least a part rotatable and in different angular positions fixable on the shaft is held.
  • the object of the invention is therefore a device of the beginning specified type to create, in which the two diagonal creases at the ends of the hose pieces if possible the setting of the length of the leading diagonal creasing line Make only one pair of creasing rollers on the end cuts to let.
  • this object is achieved at the beginning of a device specified type solved in that on each shaft cylindrical shell-shaped segment of a second creasing tool and that the one segment is helical with a groove and the other segment is helically provided with a web, those in the contact area of their surface lines that described by them Envelope cylinders come into engagement with each other.
  • the device according to the invention is characterized in that the individual sections of the segments carrying the creasing tools without hindrance by the second creasing tool for adjustment the desired length of the leading diagonal creasing line allow to twist relative to each other.
  • a particular problem is that of hiring desired length of the crease line rotatable disks or segments in the correct angular position on the shaft to fix.
  • the invention provides that each have an end hub or disc rotatable each shaft is connectable and that the package of the rotatable Segments for its fixation against the hub by means of a clamping device is exciting. Even the one that cannot be turned on its own Each shaft connectable hub or disc can be a segment of the wear the first creasing tools.
  • each of the two hubs which can be connected to each shaft in a non-rotatable manner a cylindrical shell-shaped device having a creasing tool via a web Segment that contributes in the opposite direction each of the cylindrical shell-shaped segments of the second creasing tool protrudes.
  • Each clamping device can consist of disc springs that are on the one hand on a collar of the shaft and on the other hand support a sliding bush mounted on the shaft, which in turn relate to the rings or Supports washers.
  • the socket In order to twist the rings or disks to remove this acting voltage, the socket with be provided with an annular flange to which one in the frame mounted and the bush moving towards the disc spring Rocker arm attacks.
  • Each rocker arm can consist of a two-armed There are levers that can be pivoted by an eccentric is.
  • the segments of the first grooving rings or washers are provided with grooves concentric to the shafts into which grasp bolts attached to adjacent rings or washers.
  • the creasing tools of the segments expediently rest on a spiral line if the bolts at one end of the Grooves. In this way, the rings or disks easy and quick for the purpose of lengthening the length align a crease line relative to each other.
  • the parts of the creasing tools of both rollers are preferably in divided segments rotatable relative to each other.
  • the segments both parts of the creasing tools so offset from each other that they cannot interfere with each other, if the bolts are at the other ends of the grooves.
  • a such twisting of the segments of both co-operating rollers a creasing tool is required, for example, if the two tool parts that perform the diagonal creasing in the case of narrower pieces of hose, they are closely approximated.
  • the distance between the two perpendicular crease lines can only be done by rotating the segments of the first creasing tools can be set. But the distance can also be changed can be set that the cylindrical shell-shaped segments of the second creasing tools by a releasable clamp connection with the Waves is connected.
  • each shaft from a hollow shaft and one supported in it Shaft exists that the first creasing tools on the hollow shaft stored or fastened and the second creasing tools on the the hollow shaft projecting from the shaft are fastened and that each shaft and each hollow shaft drive them separately Gears is provided. This configuration enables it, simply by relative rotation of the gears set the distance between the diagonal creasing lines or to adjust.
