摘要:
A method of making a security element (1) for a data carrier where a substrate (2) is overlaid on a visible layer (3). An image outlining member (4) or a tool head (8) is positioned on said visible layer (3) and energy is applied to the image outlining member (4) or tool head (8) to melt the visible layer and form an outline of an image. Material not required to form the image is removed, so providing the image on the substrate (2).

A structure of napkin having laces and the method for making the same, comprising a napkin body (1) made by fabric and used for wiping when dining, hemmed edges (2) made on the periphery of the napkin body by an embossing and hemming means (4), and special geometric motifs (3) arranged by many holes and patterns distributed in predetermined positions over the napkin body. With the above structure, a variety of geometric motifs can be embossed on the napkin body without folding the edges of the napkin body and increasing the thickness thereof. Thus, the hemmed edges can be easily made.

A die for use in heat welding a plastics motif to a textile base as a first welding ledge extending along a first, substantially planar face of the die, the welding ledge having a coplanar welding surface lying at least 4 mm. above the die face and having a cutting edge projecting above the welding surface to a height of at least 0.3 mm. The width of the welding surface is not less than 0.5 mm and is preferably between 1.5 mm and 3 mm. The die also has further welding ledges on which the welding surface extends the full width of the ledge. Each welding surface serves to weld the plastics material to the textile whilst the cutting edge severs excess material from the plastics motif along a welded line.

A flexible irrigation hose comprises at least one tubular layer (2) made of a first polymeric material having an outer surface (3) with a plurality of decorative elements (4) stably associated therewith. The decorative elements (4) consist of at least one sheet layer made of a second pigmented material. A method and a plant for decorating a flexible irrigation hose.
摘要:
A method and apparatus for punching out labels from a woven tape. According to the invention, the woven tape, in the form of a continuous ribbon (1) or the like, is fed step by step towards an ultrasonic-wave cutting device (4), where the ribbon (1) is centered and pressed between a first cutting element (6) defining the outline of the label (2) and a second cutting element (5), aligned with the first, constituting an ultrasonic wave emitter; an ultrasonic pulse of adequate frequency and intensity causes the cutting of the label (2) and simultaneous cold welding all around the edges.
