Abstract:
Laser-inscribable film, comprising a contrast layer based on a cured acrylate coating composition and, arranged above the contrast layer, an engraving layer, where the cured acrylate coating composition is based on a composition comprising from 30 to 80% by weight of a trifunctional oligomer A, from 0 to 20% by weight of a trifunctional monomer B, from 1 to 30% by weight of a difunctional monomer C, and from 2 to 40% by weight of a colorant pigment.
Abstract:
In a process for the profiling of a grinding worm (1) with at least two grinding width zones (4, 6) with differently modified thread profile for the grinding of spur and helical gears with three-dimensionally modified flank profile, the grinding width zones (4, 6) are arranged overlapping in order to gain optimum exploitation of the grinding worm width (3). In one variant, profiling of the grinding worm (1) is performed with an abrasive coated profiling gear (25) with a tooth flank geometry and facewidth differing from that of the workpiece to be ground. By suitable selection of the diagonal ratio and the allocation of the width zones (28, 29) of the profiling gear (25) to the grinding width zones (4, 6) of the grinding worm (1), it is possible to adapt the modifications of the grinding worm flanks to the requirements of the workpiece without having to alter the flank geometry of the profiling gear (25). In another variant the grinding worm (1) is profiled in a first stage across its entire width (3) with the desired profile form of the roughing zone, and in a second stage the finish grinding zone (36, 37) and the adjacent transition zones (34, 35) of the right and left flanks of the grinding worm (1) are finish profiled by means of NC controlled line by line profiling with a form dressing roll (40).
Abstract:
A tear removal aid and method improve the removal, more particularly manual removal, of a length of adhesive tape which has a textile carrier. The textile carrier has a two-dimensionally extended body having a flexural strength which corresponds at least to the flexural strength of a steel sheet having a thickness of 0.25 mm, preferably 0.50 mm, more preferably of 1.00 mm.
Abstract:
A grinding worm for the continuous generation grinding of a work piece is provided with mutually overlapping rough grinding and finish grinding zones arranged along the worm's axis, the finished grinding zone being provided with a three-dimensionally modified flank geometry having a width related design.
Abstract:
The invention relates to a method for producing a multi-coloured laser-inscribable film, wherein a first lacquer layer is applied to a support and at least one other lacquer layer is applied to the first lacquer layer. The colours of two lacquer layers that are superimposed differ from each other. According to the invention, the first and the other lacquer layers are respectively formed from a printing lacquer, the printing lacquer layers are designed such that they have absorption rates which differ up to 20% and the printing lacquers are printed thereon to form the lacquer layers.
Abstract:
A method for producing a multi-layered film wherein an engraving layer is partially printed onto a support film. Said engraving layer may be made of a UV-cured printing ink and a cover layer is applied to the entire surface above the partial engraving layer, optionally, directly to the partial engraving layer. The cover layer may be made of a UV-curable printing ink and may be printed over the engraving layer. A film produced by such method is also disclosed.
Abstract:
An adhesive tape having a carrier and an adhesive layer applied to at least one side of the carrier, wherein the carrier is a thread-stitched web nonwoven carrier produced from a preconsolidated base web of staple fibers. Mutually parallel threads are stitched into the base web to form the final thread-stitched web nonwoven carrier, wherein the ultimate tensile strength of the preconsolidated but not as yet overstitched base web is less than 2 N/cm. In embodiments, the ultimate tensile strength of the preconsolidated but not as yet overstitched base web is below 1 N/cm or below 0.5 N/cm.
Abstract:
A method produces an adhesive tape having a textile carrier and a pressure-sensitive adhesive coated on one side thereof.
