Definitions

  • the present invention can be applied in any technical field in which it is desired to wind a chain, consisting of a series of links, around a chassis- carried bobbin, it should be mentioned that the invention has been developed to form part of a method and part of an apparatus for the production of non-allergenic elements, and then particularly metallic elements that are intended to come into direct contact with the skin of human beings.
  • Another technical problem resides in the ability to realise the significance of and the advantages afforded by effecting said deflection with the aid of a fully or partially cylindrical centre or intermediate part of two rounded edge-associated and flange-connecting parts.
  • the present invention thus relates to an arrangement for winding a chain, consisting of a series of links, around a chassis-carried bobbin, wherein said bobbin is arranged for axial reciprocal movement during a winding stage, so as to enable the chain links to be positioned tightly against each other in mutually related turns, and also an arrangement which in addition includes the requirements given in the introduction.
  • deflection of a chain section shall take place within a central or intermediate region of a chain section situated upstream of the bobbin and orientated to provide a deflection angle smaller than 160 degrees, even when successively oriented extensions of a chain has completely filled the bobbin.
  • a length-measuring or distance-measuring device which is adapted to measure a distance between a chassis-fixed point and a chain section and, when a measured distance deviates from a predetermined value, to cause the bobbin to be moved axially so as to obtain said predetermined distance, through the medium of a control unit.
  • the lowermost part or the lowermost point of the arc is sensed by a sensing or length-measuring unit connected to said control unit, and when the point sensed is lower than a predetermined value, the circuit regulates the rotational speed of the rollers advancing said chain section to cause an increase to speed at which the rollers rotate, or vice versa.
  • An adapted extension of a chain section upstream of the bobbin is obtained by activation of a circuit that regulates the speed at which the bobbin rotates.
  • Those advantages primarily characteristic of an arrangement reside in the creation of conditions for enabling, via adapted axial displacement of a bobbin in relation to a chassis, conditions to be created such that the links of a chain will be positioned in tight relationship in respective turns around the bobbin, by deflecting each an every chain section in an upstream central or intermediate region of said section and by measuring the distance between a chassis-associated fixed point and respective chain sections, so as to create conditions, via a measured distance and a control unit actuated in accordance therewith, in which the bobbin is moved axially such as to obtain said pre- determined distance.
  • the bobbin 3 is arranged to move axially, backwards and forwards, in relation to the chassis 2 during a chain-winding sequence, as will be described in more detail below with reference to fig. 5.
  • the unit 5 is comprised of two rollers 5a, 5b, which have soft peripheral surfaces 5a', 5b' and which control the position of consecutive chain sections, wherein a chain section 4b is connected to or coordinated with a chain section 4a and located upstream of said section, is caused to pass between said rollers.
  • the rollers 5a and 5b may be displaceable in an axial direction, to avoid wear.
  • One suspension point 9 of said further chain part 4d is comprised of an elevator 10, and the second suspension point 1 1 of said further chain section 4d is comprised of two co-ordinated rollers 12, 12a.
