Abstract
A method for manufacturing a brush head (). The method includes molding a tuft carrier () having at least one retention element () that are positioned relative to a handling plate (). Excess material () may be removed from the tuft carrier. The retention elements are loaded into recesses of the handling plate. A bristle tuft () comprised of a plurality of bristles () is inserted into the opening () of each retention element. A proximal end () of each bristle tuft () is bonded together with at least a portion of the proximal side () of each corresponding retention element () to form a merged proximal end head portion () that secures the bristle tufts and retention elements together as a plurality of merged tuft assemblies (). A platen () of a neck () is positioned in relation to the merged tuft assemblies using a cavity in a base plate. A matrix material () is overmolded to at least partially encompass the platen and the merged tuft assemblies and form the brush head.
