摘要： Apparatus for measuring tension or a tension alteration in a paper web. At least one measurement device includes a number of measurement bodies and a number of fluid supply devices, which are intended to apply a fluid pressure to the web. The fluid supply devices are so arranged as to subject the web to an essentially constant fluid pressure in order to provide a fluid cushion between the web and the measurement bodies. The measurement bodies are so arranged as to apply pressure to the web without making contact and are so arranged to be capable of displacement. The position of the measurement bodies in the normal direction of the web is altered depending upon variations in the constitution of the web. A method for measuring web tension and a machine including apparatus for measuring web tension are also disclosed.

摘要： A process and apparatus for continuously measuring the tension of a filament being displaced from one point to another comprising applying a lateral pressure to the filament to displace it from its trajectory and measuring of variations of the counter-pressure exerted by the filament. The pressure is exerted laterally by producing between the filament and a support a flow of gas whose values of flow rate and pressure are such as to form a gas film between the filament and the support. The filament rides on this gas film. Measurement is made of the variations of one of the values of flow rate and pressure with respect to the corresponding value in the absence of the filament. A direct read-out of filament tension can be made.

摘要： A thread-like element is advanced over one side of and in contact with a member which can yield in direction towards this one side. A stream of gaseous pressure fluid is directed against an opposite side of the member in direction towards the one side, and the backpressure of the fluid which develops at the one side is measured. Depending upon the pressure that has been measured, a greater or lesser retarding force is exerted on the thread-like element, this force being a function of and varying in dependence upon the measured backpressure.

摘要： This invention is directed to obtaining and maintaining a constant tension on yarn being taken from a spool thereof and directed to a sewing needle, effected by employing a constant speed roller revolvaly driven around an axis variably movable to and fro relative to fixed yarn guides before and after the roller, movement of the axis away from the guides placing greater tension on the yarn and moving toward the guides (or toward an intermediate position between the guides) lessening tension on the yarn, the movement of the axis being effected by force of high pressure or high leverage and being responsive to a minor low pressure initiatable of the high pressure system, the high pressure being constant but the valve(s) directing the flow of fluid for to and fro action of the axis being controlled by a piston-like valve responsive to the low pressure, and there being subsequent to the roller and guides in yarn-flow series a pulley mounted on one end of a lever arm pivoted on a fulcrum element about central of the arms length and at the opposite end of the arm there being a blade-valve for turning on and off the low pressure fluid to opposing bellows between which the fulcrum is mounted in suspension therebetween fixedly, whereby upon the tension on the yarn running around the pulley becoming greater or lesser, the blade-valve opens or closes to release low pressure fluid which released fluid moves the fulcrum upwardly or downwardly by effecting bellow action negatively and positively on the respective opposing bellows, while concurrently the released or terminated low pressure acts on the piston valve for turning on or off the high pressure for moving to or fro the axis of the roller between the fixed guides.

摘要： A multi-item detector for use with a document feeder for feeding documents along a document path includes first and second vacuum heads having juxtaposed faces and being spaced apart on opposite sides along the document path. Each head is adapted to be connected to a vacuum source. The faces of the vacuum heads include a plurality of apertures through which a vacuum is applied for drawing documents into contact with either the first or second vacuum head. A first vacuum sensor is coupled to the first vacuum head. A second vacuum sensor is coupled to the second vacuum head. Each of the sensors have an on-state and an off-state for sensing an increase in vacuum level when a document contacts one of the vacuum heads in order to place the sensor in the on-state. When multiple documents are present in the document path, both sensors are in the on-state.
