Abstract: A winding machine for a continuous web includes at least two support rollers defining a bed for the wound web. At least one roller has a rotatable, perforated roller shell. A stationary pressure box disposed inside the roller shell which is opened toward the inner surface of the perforated shell and is connectable to a source of pressure air. A further longitudinally extending packing closes the bottom of the gap between the first and second rollers. Longitudinal packings at the pressure box define a pressure zone extending approximately from the further packing to the place where the round roll lies on the one support roller. A suction zone is defined at the support roller upstream in the direction of roll shell rotation from the pressure zone. A grid of walls along the pressure zone in the pressure box define axially shorter length individually pressurizable zones connectable to a pressure source. In an alternate embodiment, three support rollers define two roll beds.

Abstract: Apparatus for winding or unwinding of a web includes a support device having at least two king rolls and which may include a supporting belt. A winding roll of a web to be wound or unwound by the apparatus is supported by the king rolls such that a press gap is formed with at least one of the king rolls. At least one of the king rolls has a support body and a shell made from a soft, elastic material, the shell having a plurality of cavities, the cavities opening in a direction opposite a peripheral surface of the support body. In one embodiment the supporting belt includes cavities which may be filled with compressible material. In another embodiment the supporting belt includes a cover layer and a base layer with the base layer being softer than the cover layer.

Abstract: A device for feeding the leader of a paper web from below to a rolling machine roll, with a number of guide plates which direct the web leader upward and which, viewed in the web running direction, are arranged increasingly more steeply and eventually vertically, additionally with blowing organs that feature each a hollow body arranged transverse to the web running direction and a number of nozzles arranged in the web running direction, and which, viewed in web running direction, are arranged each between two overlapping guide plates. The invention is characterized in that at least the blowing organ which, in the web running direction, precedes the first vertical plate features turbulence-generating nozzles.

Abstract: A winder for winding a running paper web is provided that includes a first and a second support roller that together form a winding bed to hold a paper roll with the paper web wound around the first support roller. The winding bed consists of the first and the second support rollers. The first and the second support rollers are fixed into position with the second support roller being positioned lower than the first support roller so that a plane through the axes of the first and the second support rollers forms an angle with a horizontal plane. The first and the second support rollers each having a liner. The liner of the second support roller is considerably more deformable than the liner of the first support roller.

Abstract: The dry end of a paper making machine includes a first dryer group of heatable web dryer cylinders followed by a second dryer group of heatable dryer cylinders. Each dryer cylinder has a neighboring suction guide roll. Respective first and second web support belts are provided for the first and second dryer groups. The paper web to be dried alternately passes between a dryer cylinder and the neighboring suction guide roll, such that the web comes into direct contact with the dryer cylinders. A transfer region is located between the two dryer groups at which the web is transferred from the first to the second web support belt. A displaceable guide roll in the transfer region is associated with at least one of the first and the second web support belts.

Abstract: A guide roll for a porous belt, for instance for the drying wire of a paper machine, is described. A perforated roll shell rotates about a stationary air guide box. The guide box has two air chambers which extend across the length of the guide roll. One air chamber serves the discharge of blowing air and the other air chamber serves the intake and removal of suction air. Contained between the air guide box and the roll shell is an annular space in which a blowing zone and a suction zone are defined by longitudinal seals. Considering that blowing air and suction air may have different temperatures, the two air chambers of the air guide box are movable axially relative to each other.

Abstract: A coating device where the pressurized coating space formed between the doctor element and the material web and/or the counter roll carrying it is defined by a regulating plate on the inlet side relative to the material web. A guide device is so arranged in the coating space that coating mixture will circulate around it on all sides in one direction of rotation. The guide device generally leaves only relatively narrow flow channels open in the coating chamber so that harmful turbulent flows are extensively avoided which through pulsating air inclusions might lead to defects in the applied coating.

Abstract: The clamping head features a cylindrical section engaging the winding core with a threading which digs in inside the core and a subsequent collar forming a stop for the end face of the core. To obtain a form fit which spares the core, the threading is fashioned as a round threading.

Abstract: A clamping head is equipped with angular spreading bodies which engage a winding core. Impingement of the winding core end face on a stop moves the spreading bodies longitudinally on a bevel of the clamping head core against spring force, thereby spreading the spreading bodies so as to engage the inside circumference of the winding core. To that end, the clamping head features a sleeve-shaped part which centers the winding core and is provided with longitudinally extending slots for the angular spreading bodies. A shank of each spreading body, extends radially outward, forms at least indirectly the stop for the winding core end face. Longitudinally movable in the slot, the other shank of the spreading body has a projection which protrudes radially inward and interacts with the bevel of the clamping head core so as to cause the shank to move beyond the peripheral surface of the sleeve-shaped part as the projection runs onto the bevel.

Abstract: A clamping head is shown having a cylindrical portion engaging an interior portion of an associated winding tube and a collar or flange which axially abuts against the axial end face of the associated winding tube; extending axially between the cylindrical portion and the collar or flange is a conical portion of longitudinally extending serration; the teeth of such serration start, from the diameter of the cylindrical portion, beginning with a zero cross-section and increase toward the collar or flange with steadily increasing geometrically similar cross-section.

Abstract: In the dryer section of a paper making machine, the paper web is pressed against the drying cylinders by means of an air-permeable endless support band. An air blast apparatus extends transversely of the paper making machine and creates an air flow which is directed generally across and through the support band and onto the paper web. The air blast apparatus has at least one blow orifice in the form of a ring slot with two longitudinal slots extending generally longitudinally of the air blast box or housing of the air blast apparatus, and at least generally transversely of the paper web and the support band. The blowing directions of the two longitudinal slots may be at different angles with respect to the running direction of the support band.

Abstract: An air guide box for the dryer section of a paper making machine is arranged as generally between two succeeding drying cylinders and along a continuous support band or belt which supports the associated paper web to be dried; the air guide box has an end of generally wedge-like configuration which extends at least some distance into the gore-like space as exists in the region where the support band or belt runs onto the next drying cylinder; a first gap exists generally between a first wall of the guide box and the running support band or belt while a second gap exists as between a second wall of the guide box and the juxtaposed surface of such next drying cylinder.
