Method for producing a toothbrush and toothbrush

摘要

In the production of toothbrushes, the neck part and the head part are bent relative to each other from the original shape thereof by a predetermined angle (α) in the hot state of the toothbrush body. Thereafter, the force applied to the toothbrush body by the stretching device in order to bend the toothbrush body is removed so that the toothbrush body can bend back into the original shape thereof. The risk of fractures, in particular brittle fractures, can be greatly reduced by said action. The method is advantageous, in particular, if the toothbrush body was heated during processing by ultrasonic welding.

1. A method for producing a toothbrush, in which a toothbrush body having at least one head part and a neck part connected to the head part and carrying it is produced, the head part is provided with a carrier plate carrying bristles and the carrier plate is fixed to the head part by means of welding, and a force is then exerted on the toothbrush body, wherein the neck part and the head part are bent relative to one another from the original shape by a predetermined angle (α), still in the hot state of the weld zone, by means of the force, and the force is removed after the bending process so as to allow the toothbrush body to bend back into its original shape.
