  • Patent number: 4317546
    Abstract: A coiling apparatus converts longitudinal fastener strips into wound up coils. For this purpose the strip is fed through a guide track substantially tangentially to one or the other coiling or winding mandrel which may be brought into coiling or winding position by a pivot lever which carries two mandrels, one at each end. A clamping lever holds the strip so that it runs onto the mandrel.

  • Patent number: 4156335
    Abstract: Strip sections holding securing elements such as nails or screws are stacked, for example, in cartons so that the nail heads or screw heads come to rest in alternate opposite directions. For this purpose the strips slide down an inclined guide chute in a given direction until the heads are held by support elements which are movable alternately and laterally outwardly substantially at right angles to said given direction. Thus, one support element still supports the heads while the other support is withdrawn from the holding position whereby the strips, as they fall downwardly, rotate alternately, through an angle of 90.degree. whereupon the strips are intercepted, for example, by a tiltable chute.
