the present invention relates to a method for rounding the bristle end of a brush section (v) comprising a plurality of bristles (4), the method comprising providing a focused laser beam (11) that propagates along a geometrical main propagation direction (pd) that has a main irradiation site (12), providing relative movement between one end of each bristle (4) and the main irradiation site (12) of the laser beam focused (11) so that the end of each bristle (4) is moved through the main irradiation site (12) in a path (p) that has a main component transversal to a longitudinal extension (le) of the bristle (4) , in which the focused laser beam (11) is directed so that the main geometric propagation direction (pd) has a main component transversal to the longitudinal extension (le) of the respective bristle (4) that has its end at the irradiation site main (12), where an arr End edging is provided by the focused laser beam (11) which heats the end and causes it to partially melt and form a rounded end, providing relative movement between the main irradiation site (12) and the brush section (1?) Along a direction (l) that has a main component that is transversal to the path (p), thus submitting, in sequence, the ends of the plurality of bristles (4) to the focused laser beam (11) providing thus, a brush section (1?) which has rounded end bristles (4). the description also refers to an appliance.a presente invenção refere-se a um método para arredondar a extremidade de cerdas de uma seção de escova (v) que compreende uma pluralidade de cerdas (4), sendo que o método compreende prover um feixe de laser focalizado (11) que se propaga ao longo de uma direção de propagação (pd) principal geométrica e que tem um local de irradiação principal (12), provendo um movimento relativo entre uma extremidade de cada cerda (4) e o local de irradiação principal (12) do feixe de laser focalizado (11) de modo que a extremidade de cada cerda (4) seja movida através do local de irradiação p
