A brush head () and a method for manufacturing a welded tuft assembly () for a brush head (). The method includes insertin g a bristle tuft () into an opening () in a retention element (). A proximal end of the bristle tuft () and a proximal side () of the retention element are laser welded to at least partially melt the bristle tuft and at least a portion of the proximal side of the retention element together to create a merged proximal end head portion () that holds the welded tuft assembly together.

Brush head manufacturing method

A brush head () and a method for manufacturing a brush head. The method includes forming a plurality of retention elements () each having an opening () therethrough. The retention elements () are positioned into corresponding recesses of a plate. A bristle tuft () is inserted into each of the openings of the retention elements. A proximal end () of each bristle tuft is bonded to the corresponding proximal side of the retention element to form a merged proximal end head portion () that secures the bristle tufts and the corresponding retention elements together as a plurality of merged tuft assemblies (). A neck () of the brush head is positioned in relation to the merged tuft assemblies. A platen () of the neck and the merged tuft assemblies is at least partially encompassed in a matrix ().

A brush head () and a method for manufacturing a welded tuft assembly () for a brush head (). The method includes inserting a bristle tuft () into an opening () in a retention element (). A proximal end of the bristle tuft () and a proximal side () of the retention element are laser welded to at least partially melt the bristle tuft and at least a portion of the proximal side of the retention element together to create a merged proximal end head portion () that holds the welded tuft assembly together.

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.

Brush head manufacturing methods using a molded tuft carrier and base plate

A brush head () and a method () for manufacturing a brush head. The method () includes stamping () a plurality of openings () into a strip or roll of backing material (). A bristle tuft () is inserted into each of the openings in the backing material. A proximal end () of each bristle tuft is bonded to a proximal side () of the backing material to create a merged proximal end head portion (). Excess portions of the backing material are removed to form a plurality of carrier elements () about the openings from the backing material. The carrier elements form a plurality of merged tuft assemblies (). A platen () of a neck () is positioned in relation to the merged tuft assemblies. A matrix material () is injected around the platen and the merged tuft assemblies to at least partially encompass the platen and the carrier elements of the merged tuft assemblies.
