  • Patent number: 9156984
    Abstract: A method for preparing a plurality of coated binder units wherein each of the coated binder units comprises a core of a binder coated with a layer of coating material, which method comprises the steps of: (a) providing a coated binder which comprises a core of a binder coated with a layer of coating material; and (b) dividing the coated binder into the plurality of the coated binder units by means of a system which comprises a first and a second loop that engage over part of their lengths and rotate in opposite directions, the first loop comprising a first repeating sequence of interlinked molds and the second loop comprising a second repeating sequence of interlinked molds, whereby the coated binder units are formed by welding edges of the coating and cutting the extrudate into pieces in a region where the first and the second loops engage. The invention further relates to said system.

  • Publication number: 20110115116
    Abstract: A method for preparing coated binder units, wherein the coated binder units comprise a core of binder coated with a layer of coating material, is disclosed. The method comprises steps of: (a) co-extruding the binder and the coating material, thereby producing an extrudate wherein the binder is coated with a layer of coating material; and (b) optionally, shaping the extrudate, into coated binder units.
