摘要： Provided is a process for producing a nonwoven fabric. The process includes extruding a plurality of filaments from a spinneret, the filaments being at least bicomponent filaments; depositing the filaments to form a nonwoven fabric on an element collecting the filaments; performing a bonding of the nonwoven fabric; increasing the thickness of the nonwoven fabric by crimping at least part of the filaments by heating the nonwoven fabric; and, preferably performing a setting of the nonwoven fabric, wherein the bonding and the increasing the thickness steps are performed substantially simultaneously by means of a heated calendar. Also provided is the nonwoven fabric formed using the process and an apparatus for carrying out the process.

摘要： The purpose of the present invention is to provide a method of producing a fabric for an air bag that, during high-pressure deployment at high speed, maintains low air permeability as an air bag and is capable of maintaining the low air permeability even after exposure to heat. This method of producing a fabric for an air bag comprises the steps of: 1) weaving with high tension warp threads at 0.20 cN/dtex to 0.65 cN/dtex in a water jet loom, 2) carrying out a washing treatment step at 80° C. or lower or not carrying out a washing step, 3) drying at a temperature of 110° C. or lower, and 4) carrying out calendering processing.

摘要： A method of treating a web includes directing the web toward an apparatus having a first roller and a second roller together defining a nip. The first roller is rotated in a first direction and includes two ends, a length extending between the two ends, a raised area adapted to treat the web, and a bearer ring. The bearer ring extends around the circumference of the first roller and is disposed at a location between and spaced from the ends of the first roller. The second roller of the apparatus is rotated in a second direction opposite to the first direction. The web is fed to the nip of the apparatus such that the web is contacted by the raised area on the first roller to treat the web.

摘要： A cylinder has a roll shell that rotates around a fixed central axis. A first chamber arranged inside the cylinder is filled with liquid and transfers a supporting hydraulic force from the central axis to the shell. The first chamber is linked by a throttle to a second chamber located as well inside the cylinder, and in which is arranged for example a hermetically closed rubber hose filled with gas, so that the second chamber is at all times only partially filled with liquid. Thus, the volume of liquid contained in the second chamber can rapidly change when there is a change of pressure in the first chamber, so when the shell tends to vibrate, liquid flows back and forth through the throttle, converting wave energy into frictional heat by means of fluid friction, and thereby damping the vibration.

摘要： A gas burner includes a burner tube which has on one side a row of burner nozzles aimed against a surface to be heated. In the interior of the burner tube, at least one slider is arranged which can be moved from outside the burner tube along the tube and by means of which the end burners of the row of burner nozzles can be shut off from the gas supply which is supplied the center of the burner tube, so that the row of the burner nozzles can be adapted to the width of the surface to be heated, e.g., to the width of a web when the burner tube is used to heat a hollow roll used to treat a web.

摘要： A roll which can be used in a calender to bear upon a web of textile material, paper or the like while the web travels between the peripheral surface of a floating shell of the roll and a counterroll. The shell surrounds a non-rotatable shaft which carries several rows of discrete electromagnets extending in parallelism with the axis of the shaft and along an arc of at least 200 degrees, as considered in the circumferential direction of the shaft. The electromagnets can be energized to a different extent so as to subject the magnetizable material of the shell to forces of different magnitude and to thus counteract the tendency of the shell to undergo deformation in response to the action of forces which act radially of the shell or which tend to impart to the shell vibratory movements. Additional electromagnets can be provided to cooperate with a radially inwardly extending flange at one end of the shell to hold the latter against excessive movements from an optimum axial position.

摘要： A controlled deflection roll comprising a tubular-shaped flexible roll shell rotatable about a fixed support. The roll shell is supported by pressure elements arranged in a pressure plane. The pressure elements are movable relative to the fixed support in such pressure plane and serve to exert a pressure force. The roll shell is fixedly retained at its ends to preclude movement perpendicular to the pressure plane. At least one device for influencing laterial deformation of the roll shell is arranged at the support. Such device is equipped with at least one impact or contact surface and cooperates with the inner surface of the roll shell.
