Method for the laser marking of trousers, comprising: folding the trousers by the crotch area such that the two halves (1a, 1b) of the trousers rest superimposed in a flat manner, arranging a first half of a first side of the trousers in a marking area of a laser module (2) in a position facing a laser equipment (21) for marking said first half (11a). This method comprises the automatic rotation of the trousers and the arrangement of a second half (11b) of the first side in a position facing a laser equipment (21) that performs marking of predetermined areas (10b) of said second side (11b) of said first face. The invention also comprises a device for the laser marking of trousers according to said method.
摘要:
An imaging device for projecting individually controllable laser beams onto an imaging surface movable in an X-direction. The device includes a plurality of semiconductor chips each comprising a plurality of laser beam emitting elements arranged in a main array of M·N. The chips are mounted such that each pair of adjacent chips in the Y-direction are offset from one another in the X-direction and, if activated continuously, the emitted laser beams of the two chips of said pair trace on the imaging surface a set of parallel lines that are substantially uniformly spaced in the Y-direction. In addition to the M·N elements of the main array, each chip comprises at least one additional column on one or each side, each additional column containing at least one selectively operable element capable of compensating for any misalignment in the Y-direction in the relative positioning of the adjacent chips on the support.
摘要:
The invention relates to a container handling machine (1) comprising: - at least one operative unit (19) configured to receive a container (3) filled with a consumable, in particular a pourable product, and closed by a cap (5) in turn having at least one region (17) provided with colouring pigments (18) set in a deactivated state, in which they are transparent; - transportation means (7) for advancing the operative unit (19) along a given path (P); and - activation means (35) selectively actuated while the operative unit (19) is advanced along said path (P) to supply an activation energy to at least a zone of the region (17) with pigments (18) of the cap (5) so as to set at least a part of such pigments (18) in an activated state, in which the pigments (18) have predetermined colours.
