    摘要: A method for forming a roller bearing of very small axial dimension and high load-carrying capacity, and applicable also to a large-diameter roller bearing, comprising inserting the rollers into the circumferential guide and rolling track of the outer race and holding the rollers in position by two opposing lateral shoulder-forming spring rings of small thickness which are snap-inserted into corresponding inwardly flared grooves provided in the opposing faces of the bearing outer race. The rings being locked in position by using suitable dies to axially press annular appendices which define the mouth of the annular grooves. Modifications to this method are provided, and the roller bearings obtained in accordance with the invention are described.

    摘要: A modulator for controlling high-speed rotary dobbies of the type which control the dobby main shaft's motion by transmitting power from a drive shaft through pivotable rocker supports rotatably driven by the drive shaft and engaging conjugate cams so that the drive shaft's uniform rotary motion is converted into non-uniform motion of the dobby main shaft. This is caused by the conjugate cams, which cause the rocker supports to pivot. The rocker supports are mounted so as to accommodate this rocking. The two rocker supports are connected to the dobby main shaft by two connecting rods hinged by pins on one of the rocker supports and on an appendix of the main shaft respectively, these connecting rods being disposed antisymmetrically to each other in accordance with a particular geometry.

    摘要: An apparatus for rapidly and simultaneously, coupling and uncoupling loom heald frames, of varying length, to and from their respective drive bell cranks. Each heald frame attaches to more than one head of a flexible tie-rod, which in turn, extends down to adjustment sliders which are connected to the drive bell cranks. During the heald frame coupling and uncoupling from a locking apparatus at the head of the flexible tie-rod, two tilting jaws keep all of the flexible tie-rods in a rigid vertical position.

    摘要: A control system for a plurality of tuck-in selvedge forming devices in a loom having a variable reed beat-up position includes a main shaft, a drive shaft connected to all the tuck-in selvedge forming devices, a modulator driven by the main shaft and having an output shaft which pauses at least once during each revolution of the main shaft, as well as a coupling unit rotatable with the drive shaft and operative to be selectively rotatably coupled to the modulator output shaft so that the drive shaft is driven by the main shaft. The coupling unit includes a ring fixed to the drive shaft and a first cover pivoted to the ring so that a key can enter into the recess of the modulator output shaft to rotatably couple the coupling unit to the modulator output shaft during its pauses. A second lever is biased so as to follow contours of a control cam and prevent the first key from entering the recess of the modulator output shaft. An electromagnet controlled by a logic unit cooperates with the second lever to prevent the second lever from engaging the first lever.

    摘要: A control device for rotary dobbies in which a key has a transverse groove of width equal to the thickness of a control ring with which it cooperates plus the length of travel undergone by the key in its insertion into or withdrawal from radial grooves in a big end of a main crank arm or in a drive shaft. The control ring has an elliptical shape and is fixed onto a operating lever which, pivoted on a minor axis of an ellipse and retained in its rest position by a V-shaped spring, is made to rock to one side or the other about the axis of symmetry of the spring by a pusher rod. The pusher arm is operated by a cam mechanism and moved by a needle selector controlled by a programmer, to act on one of two valleys provided in a rocking sector on an operating lever symmetrically about an axis of symmetry.
