PURPOSE:To eliminate friction variation between a rubber sheet and a machine base and unevenness of the width of rubber sheets by maintaining the delivery speed, rewinding speed and conveyor speed of the rubber sheet. CONSTITUTION:The transfer speed of a belt conveyor 5 driven at constant speed is sensed, and the revolving speed of a delivery motor 14a is so set as to equalize the sensing speed to...

PURPOSE:To obtain an apparatus having small size and high power transmitting efficiency by coupling the shaft of the prime mover with the shaft of a load through an electromagnetic joint, coupling the shaft of the load with a rotary shaft of a motor through a gear unit to connected the motor with the armature winding of the joint. CONSTITUTION:The prime mover 5 is connected to one rotor 2 of an el...

In order to prevent the edges of the crown reinforcement of radial carcass tires whose tread contains oblong elements in relief or blocks (tires for earth-moving vehicles and for drive wheels of agricultural tractors) from deforming during the vulcanization of these tires in the vulcanization mold, at least some of these oblong blocks are provided with a furrow whose depth is between 1/2 and 6/5 o...

A system for preventing the overheating of an electromagnetic clutch of an internal combustion engine mounted on a vehicle caused by slipping of the clutch for a considerably long time. The electromagnetic clutch has a drive member secured to a crankshaft of the internal combustion engine, a driven member adjacent to the drive member, and a magnetizing coil provided in one of said members. The hea...

PURPOSE:To detect the calorific value of a clutch, promptly, for preventing the clutch from being overheated, by obtaining a speed difference between a cluth drive shaft and a clutch driven shaft so that a timer is actuated after the duration of a time set by the timer when the speed difference is above a reference value, for changing the coupling characteristic of the clutch. CONSTITUTION:A crank...

A third axial fluid jet (58) delivering a non-eddy stream, lies in the centre between the two eddy fluid stream jets (56,57) in the walls of the yarn splicing channel (54). The jet from the third point is not fitted with a tangential opening, while the other two jets face each other. Pref. the opening of the third jet (58) lies in the centre of the yarn splicing channel (54). The two eddy jets (56...

An electromagnet or solenoid includes an armature in the form of a piston guided for sliding axially in a magnet housing surrounding it. The armature has at least one bearing ring providing the slide bearing of the piston. The bearing ring is held by engagement in at least one groove in the outer surface of the piston. The groove extends axially on the piston and is open to one piston end surface ...

A method for producing an absorption body, notably for use in cases of female incontinence which include forming a core by dry depositing a layer of hot meltable thermoplastic fibers and a highly absorbing pulverulent material, e.g. a cross-linked polymer prepared from a methacrylic monomer, on a porous sheet, subjecting the layer to heat treatment to form a stable three-dimensional fiber network ...

In an arrangement for producing packages, which are used as feeding packages for twisting, it is provided that, directly in front of a cross-winding device of a wind-up device, a processing device is arranged which is controlled by yarn detectors. The yarn detectors monitor one yarn resepctively, which together form a double yarn, which is wound on the package. A yarn separating device or a device...

In a pressing device for a paper-trimming machine, in particular for three-knife trimmers for three-sided trimming of book blocks, pamphlets or the like, a press ram exerts, from a mechanical drive arrangement, via a lever arm movable about a central pivot and having a pressing rod which receives the press ram, and with intermediate connection of a spring element, a pressing force on the material ...

In order to allow an almost completely automatic loading of the packaging machines with packaging material, a conveying path (31), leading to the individual usage points on the packaging machines, is arranged above the packaging machines ("overhead"). Individual reels (26, 27, 28) or sheets (82), stacked in cassettes (84), are transported by material conveyors (41) along this conveying path (31) i...

The corrugation unit comprises partly curved blades fitted on the cylindrical surface of each drum and equally distributed over it, and in at least one row parallel with the drum rotation axis. The concave surfaces fo the curved blades face the direction of movement of the fibre material. Also incorporated in the corrugation unit are guides, located on both sides of the fibre material. Each guide ...

Coextrusion from rubber of hollow tubular structures with filament reinforcement provides composites which can be formed into spliceless bodies for pneumatic tires. The composites can be formed from one, two, three or more rubber stocks and have portions or layers which can form the body plies, sidewalls, innerliners, stabilizer ply inserts and, optionally, abrasion gum strips of tire bodies. Tire...

PURPOSE:To obtain a uniform bead filler by a method in which an annular bead wire is fitted onto the bottom force of a mold and bead filler-molding material is almost uniformly supplied around the whole periphery of said bead wire, and then said filler material is pressure molded by the top force and the bottom force. CONSTITUTION:A bead wire 5 is fitted onto the fitting part for a bead wire of a ...

PURPOSE:To detect abnormality speedily and to minimize a down time, by outputting an AC route check signal every time a route check counter goes to 0 in the end of processing, and detecting the output externally. CONSTITUTION:The route check counter 9 is provided in the software processing routine of a microcomputer MPu8. The route check counter 9 is reset to 0 in the ending of processing when a n...
