Abstract:
Describe is a method of positioning a male die member (34) on a backing rolled (14) of a stamping station (10), which backing roller co-operates with a stamping roller (12), wherein the stamping roller (12) has a die (18). Temporarily fixed to the die (18) of the stamping roller (12) is a flexible transfer male die member (24) having a fitting window (32). The transfer male member (24) is transferred from the stamping roller (12) to the backing roller (14) and fixed to the backing roller (14). The male die member (34) is then fixed in accurately fitting relationship in the fitting window (32) of the transfer male die member (24).
Abstract:
The present invention provides methods for producing a seamless embossing shim. The shim carries a pattern to be embossed on a decorative medium, such that the image on the decorative medium contains no production seams. The methods comprise several steps. First, the a flat shim is casted onto a plastic cylinder to form a plastic master with the pattern on the outer surface to form a plastic master. Second, the plastic master is used to produce a metal master by depositing a layer of metal on the outer surface of the plastic master. Lastly, the metal master is then used to formed the seamless embossing shim by depositing a layer of metal on the inner surface of the metal master.
Abstract:
The invention relates to a method for producing a structured voluminous non-woven fabric, comprising the following steps: producing a spunbonded non-woven fabric consisting of a plurality of monofilaments which are stretched only at 50 to 70% of the maximum possible stretch range to form a fiber skein and subsequent processing the raw non-woven fabric by means of a second pair of rollers (10a, b) with a metal outer jacket to improve the velvet finish. In the second pair of rollers, the positive elements of the positive roller are nops (11) arranged in rows and the surface of the negative roller has lamellas (13) which are arranged in an axial direction and provided with intermediate recesses (14) so that when the rollers roll against each other the lamellas engage in the channels left open by the nops.
Abstract:
The invention is directed to sleeves of high heat conductivity material being press fit on a water cooled shaft and held in position by pins and appropriate locking units of a specific torque.
Abstract:
Sheet material is deformed, for example crimped or bulked by feeding it to the surface of a rotating roll having a multiplicity of depressions in its surface and pressing the material against the roll surface, the material being fed to the roll at a rate exceeding the linear peripheral speed of the roll. Examples of materials which may be so deformed are filaments consisting of or containing thermoplastic polymers, woven and non-woven fabrics, thermoplastic sheets, paper and metal foils. Preferably, the roll surface consists of sintered particulate material, the depressions being the voids between adjacent particles.
Abstract:
In some embodiments, a method for manufacturing a packaging material includes forwarding a web of said packaging material through a nip provided between an anvil roller and an imprint roller which are arranged against each other, said imprint roller having a surface area including an imprinting area and a non-imprinting area, said imprinting area comprising protrusions forming an imprinting pattern. The method can further include imprinting the imprinting pattern into an outermost layer of said packaging material with said imprinting pattern as said web passes through the nip to form a visual or tactile pattern on the packaging material corresponding to said imprinting pattern. The method can further include adjusting the position of said web when said non-imprinting area of said surface area faces said packaging material The disclosure also relates to an apparatus for manufacturing a packaging material and a packaging material.
