Abstract
A method (500) for manufacturing a brush head (10). The method includes the steps of providing a plurality of bristle tuft retention elements (52), and inserting a bristle tuft (21) into each of the bristle tuft retention elements; using a heat reflection device (200) to evenly apply heat to at least partially melt the bristle tuft proximal end and, optionally, the retention element, create proximal end head portion (26) to retain the bristle tuft in the retention element.
Claims10
A method for manufacturing a brush head, the method comprising the steps of:
- inserting a plurality of bristle tufts into a tuft carrier, wherein a proximal end of each bristle tuft is inserted into a different opening of the tuft carrier;
- activating a heat reflection device having at least one heating element and at least one heat reflecting surface therein, wherein the heat reflection device comprises multiple sides to at least partially contain the heat generated by the heating element, and an opening that can be used to insert or remove the entire tuft carrier with the inserted plurality of bristle tufts within the heat reflection device to be heated by the heating element;
- placing the tuft carrier with the inserted plurality of bristle tufts into the heat reflection device;
- directing heat from the at least one heating element toward the tuft carrier with the inserted plurality of bristle tufts to at least partially melt the proximal end of each of the plurality of bristle tufts each bristle tuft;
- and,
- cooling the melted proximal end head portion.
