Abstract: A safety bar mechanism and sheet processing device having a safety bar mechanism, with which such an accident that the operator's hand is pinched between a table and peripheral devices etc. can be positively avoided whatever direction an external force exerts. The safety bar mechanism is disposed, for example, above the table on which a sheet is stacked, and comprises detector means the upper end of which is supported on a fixed part such that the detector means pivots freely in forward/backward directions and has play in upward/downward directions. When an external force works on the detector means, thereby moving the detector means upwards, forwards or backwards, a switching means is so operated as to at least stop the upward movement of the table.

Abstract: A gin stand heat detection apparatus which includes a pair of infrared thermocouples typically mounted on the main frame weldment of a gin assembly in facing relationship beside the saw cylinder assembly and the doffing roller, for monitoring the temperature of the saw blades and ginning ribs in the saw cylinder assembly.

The infrared thermocouple control panel includes a visual alarm system for notifying an operator that a high temperature condition exists at any point along the saw blades and interspaced ginning ribs between the facing infrared thermocouples. The apparatus is also capable of automatically separating the saw blades and ginning ribs in case of a high temperature event.

Abstract: The textile machine, for example a spinning machine, comprising at least one drawing system consisting of a plurality of runs, such as pairs of rollers and the like. At least two such runs each have a cylinder having markings which are detected by a sensor of a separate pulse generator. The output signal S.sub.1 of one pulse generator is applied to a count input of a counter while the output signal S.sub.2 of the other pulse generator is applied to a reset input of the counter. The counter can be reset by the output signal S.sub.2 only during a preset reset time window. When the counter has counted to the end of this time window, the counter furnishes a trigger signal S.sub.3 for an alarm and the like.

Abstract: A depilating appliance comprises a series of adjacent, closely-spaced hair-plucking disks driven by an electric motor housed within a casing which is designed to be held in one hand. The disks form a roller unit which is rotatably mounted behind a slot, grid or the like provided in one end of the casing. Superfluous hairs to be removed are engaged between the disks in a combing action, periodically gripped by deformation of the disks, then pulled and plucked-out as a result of rotational displacement of the disks.

Abstract: An emergency actuator bar extends across an opening in the housing of a lint cleaner in a cotton gin. Actuator arms which hold the bar also normally hold a trip plate in the run position. However, a workman striking the emergency bar will remove a sear on one of the actuator arms from the trip plate to permit a spring to snap the trip plate into a stop position. When the trip plate moves to the stop position, it disconnects electrical power to a motor driving the machine. The trip plate movement also applies a brake which stops the machine.

Abstract: An accident prevention system for machines having one or more movable components, such as rotatable components, has a cover by means of which access may be had to the movable component and which can be moved to an open position. A latching arrangement normally holds the cover in closed position. An electric circuit is provided including a source of electric energy, a normally open switch and an electrically energizable actuating element which can deactivate the latching arrangement. A detector senses movement of the movable component and, when it determines that the movable component is stationary, completes the electric circuit up to the switch so that when the switch is subsequently operated, the actuating element is actuated and disengages the latching arrangement to permit the cover to be opened.

Abstract: An electromagnetically actuated jaw clutch for torsionally driving the feed roll of a carding machine includes a pair of annular, rack-toothed face gears spring biased away from each other in opposed relation to establish a nonengaged position when the clutch is de-energized. Energization of the jaw clutch magnetically forces the annular face gears against each other into an engaged interlocked position for effective driving of the feed roll. A torque overload condition established by jamming of the feed roll causes the rack-toothed face gears to ride out of engagement and separate from each other. Such torque overload separation of the face gears is sensed by a proximity switch which deactivates the clutch electromagnet and selected portions of the carding machine.

Abstract: An apparatus for detecting metallic bodies in a running textile lap performs the steps of generating a high-frequency electromagnetic field; passing the textile lap through the high-frequency electromagnetic field; and deriving a sensor signal as a function of an alteration of the high-frequency electromagnetic field caused by the presence of a metallic body in the lap.

Abstract: Fibrous materials are processed to produce a homogeneous mass of fibres by using a series of clothed cylinders, the fibrous material having passed from one cylinder to another. The cylinders progressively have coarser teeth, alternate cylinders rotating in different directions and the peripheral speeds of the cylinders are progressively greater. At least one worker roller is arranged tangentially with respect to two adjacent cylinders to work the material by rotating in the same direction as the slower peripheral speed roller. The flow of air is created along the path of travel of the material to cool and assist in transporting the material by encasing the cylinders in fitting cover means.

Abstract: An apparatus for producing a uniform textile fiber sliver which is removed from a sliver supply device, for instance a card, and taken-up by a driven take-up or receiving device, wherein the fiber sliver removed from the sliver supply device is guided through a regulation drafting arrangement having a pair of measuring rolls and a driven pair of drafting rolls. One roll of the measuring roll pair is driven by the sliver supply device, and the other measuring roll is deflected as a function of a change in thickness of the fiber sliver traveling through the measuring rolls. The drive speed of the pair of drafting rolls and the receiving or take-up device is regulated as a function of the deflection of said other measuring roll, and the drive speed of the take-up device additionally is regulated as a function of the length of the fiber band between the pair of drafting rolls and the take-up device.

Abstract: A series of roller pairs in the drafting zone of sliver drafting apparatus have toothed or needlelike projections. The projections are spaced circumferentially and axially of the rollers so that projections of cooperating rollers either within a pair or between rollers of adjacent pairs are periodically interdigitated, as seen axially of the rollers, in spaced relationship as the rollers rotate at constant angular velocity. The rollers carry toothed wheels engageable for positive drive without backlash by a toothed belt. The upper rollers of the pairs are driven by a common endless loop belt and the lower rollers by a second belt. Each belt passes over a spring-loaded jockey roller which tensions the belt and which can be moved against the spring force in response to overloading tension on the belt caused by retardation of roller rotation in response to excessive fibres between a roller pair. Such movement of the jockey roller actuates a limit switch to shut off the belt drive motor.

To control the sequential motion of the above-mentioned two series of driving mechanisms, said first and second driving motors are electrically connected.

The detecting device is disposed at a position along a path of reciprocating movement of the fiber bale back and forth over the working position of a plucking roller of the bale plucker and the driving mechanism of the bale plucker is capable of being instantly stopped by a signal issued from the detecting device upon detection of a metallic substance in the fiber bale so that carrying of the fiber bale to the plucking roller can be prevented.

Abstract: The turntable on which the silver can is mounted is connected to a piston of a compressed air cylinder and air pressure is used to maintain the piston and table in preset positions. When the silver can is filled to the preset weight, the table and piston move downwardly to activate either a switch in the path of the piston or a pressure responsive switch in the air line to the pressure side of the air cylinder.
