  • Patent number: 5806676
    Abstract: A device for packaging continuous length spiral binding combs used for the binding of loose-leaf systems, in particular, annular calendars, note books, planners, catalogs or advertising papers. The package includes a carrier plate having a row of comb holders, each having opposing retaining strips pivoting outwardly to an open position for securing the binding combs and being in the shape of an H, for engaging nonadjacent combs to hold a bottom portion of the comb on the carrier plate.

  • Patent number: 5197842
    Abstract: A closing device for the bending closure of binding combs having generally C-shaped perforating members for the comb binding of single sheets or the like has a bending tool provided with two opposing bending punches or dies. The two bending punches or dies are provided with batten-like contact elements or components which at least approximately form point- or line-shaped supports for the perforating members of the binding comb. The two upper contact elements or components are designed so that they produce a greater static friction on the binding comb. The distances of the contact elements or components are in each case adjustable with respect to one another.

  • Patent number: 5059078
    Abstract: An apparatus for the combing-in and binding of punched single sheets into a prefabricated wire comb having a multiplicity of teeth bent into circles and connected to one another, which are inserted into punched-out holes in the sheets, where the apparatus includes a closing device having a movable closing beam with a counter-pressure plate for bending the prefabricated wire comb into a circular shape. Retaining elements are arranged on the counter-pressure plate or a part connected to the counter-pressure plate, which position at least a part of the teeth of the wire comb. The counter-pressure plate is slidable under the closing beam with the retaining elements positioned such that the single sheets are inserted into the wire comb for binding.
