Abstract: A method for winding a continuous material onto a supporting surface, the method being characterized more precisely by the following process steps:unwinding a material (6) from a material supply (7) and winding said material onto a supporting surface (5);the pendulum-type support (17) of the material (6,7) during the advance, permitting an automatic adjustment of a winding angle .alpha.;maintaining the tensile stress during the winding of the material (6);the cleaning and conditioning pretreatment of the material (6) carried out between unwinding and winding; andthe coating with adhesive carried out between unwinding and winding.

Abstract: A tubular body which can be applied to a cylindrical carrier body and removed from it again, being characterized in that a first layer (10) of a wound narrow strip material (6) with a first pitch (12) is covered by another material.

Abstract: A process and rotary printing machine for indirect rotogravure printing without intermediate drying, wherein the printing ink with a viscosity in the range of 80 to 1000 mPa s is supplied to the rotogravure form cylinder by a chamber doctor. Additionally, the transfer cylinder carries a covering with a closed surface, low surface roughness, low wettability and high radial compressibility.

Abstract: A process and a device for the filling of depressions on the cylindrical surface of a rotating, cylindrical body, wherein the device includes a chamber with an interior space having all approximately circular cross-section. Fluid is supplied and discharged centric to the cross-section so that a rotating fluid roller forms when the chamber is positioned on the rotating cylindrical body.

Abstract: A cover layer, for example applied to a carrier sleeve (3), is volume compressible by being formed as a unitary seamless cover layer (3) of foamed or expanded or blown material resulting in micropores or microcells of less than 0.01 mm, with a percentage of closed or individual cells to total cells being greater than 50%. This cover layer will have a bounce-back or rebound elasticity of greater than 95% and preferably has a thickness of between about 1 to 5 mm. It may be covered with a polyurethane or rubber based outer cover layer of, for example, about less than 0.5 mm thickness. The cover layer is applied by providing a base substance which is made thixotropic, stirring it and applying it in liquid form as a spiral stripe on a rotating and axially moving cylinder (5), the material being free foaming and curing as it is being applied, and when still in spreadable and somewhat flowable condition to form a uniform seamless cover layer which includes individual, unconnected micropores or microcells.

Abstract: A printing method and apparatus which use a sleeve-shaped printing form attached to a rotating body. The sleeve-shaped form conveniently permits the printing operation to be performed continuously and on both sides of the print carrier simultaneously. The sleeves preferably exhibit a number of process-specific functional layers. Exemplary layers are: (1) a supporting metal sleeve, (2) an intermediate metal layer for carrying the ink, and (3) a surface metal layer for carrying the water. Copper is an exemplary intermediate layer, and chromium is used as the surface metal layer.

Abstract: A color printing arrangement has a series of printing stations in each of which a different color is imprinted upon predetermined regions of a travelling band to form color images. A device for measuring the width of the band by sensing the edges thereof is located immediately upstream of each printing station. The width of the band at the first printing station is compared with the width at each of the following printing stations. As long as the widths at the latter printing stations are the same as that at the first printing station, the band is allowed to continue travelling unchanged. However, when the width of the band at a printing station downstream of the first printing station differs from the width at the first printing station, the band is operated upon to return the width to its original value. The reason is that a departure from the original width of the band causes the predetermined regions which are to be imprinted to be moved out of alignment with the printing devices in the printing stations.
