Title: Balloon-contracting ring for ring spinning and ring twisting machines
Inventor: SCHMIDT BRUNO DIPL ING
IPC: D01H13/30
Filed: 1983-09-06
Abstract: The invention relates to a balloon-contracting ring for ring spinning and ring twisting machines, in which lubricant is supplied from a lubricating wick by way of orifices in the inner face of the balloon-contracting ring and is absorbed by the running yarn. The object on which it is based is to reduce the outlay in terms of cleaning time as well as the outlay in terms of working time, energy and auxiliary material for the aftertreatment of the yarn and the consumption of lubricant. This object is achieved in that underneath the orifices (8) for the supply of lubricant on the inner face (4) of the balloon-contracting ring (1) is arranged transversely to the yarn draw-off direction (9) a lubricant-wiping edge (10), to which are assigned a face (11), inclined relative to the lubricating wick (5), and flow-off orifices (12) located in the inner face (4) of the balloon-contracting ring (1) above the face (11) inclined relative to the lubricating wick (5), a trough (13) is arranged between the face (11) inclined relative to the lubricating wick (5) and the casing (3) of the balloon-contracting ring (1), and the lower end (14) of the lubricating wick (5) is arranged in the trough (13) - Figure 2 -. The invention achieves the technical effect that the lubricant is removed from the running yarn, without a soiling of the machine occurring or an aftertreatment of the yarn taking place, and that the lubricant removed from the yarn is used again. <IMAGE>

IPC: E04F15/024
Filed: 1985-04-18
Abstract: A floor slab component of rectangular basic shape for propped-up floors has a lay-in frame of rectangular basic shape, the lay-in channel of which receives the edge of a floor slab. The four frame legs of the lay-in frame comprise extruded profiles which are fastened to one another in each case on their neighbouring profile end sides by means of angular corner connecting pieces. Each corner connecting piece forms a hinge, the two hinge parts of which can swing about a common hinge pin perpenidcular to the base surface of the slab component. In this arrangement, in each case two corner connecting pieces, arranged on a first diagonal of the slab component and forming a first hinge pair, have in each case two hinge parts which can swing towards each other. The two corner connecting pieces, arranged on the second diagonal, of the second hinge pair have in each case two hinge parts which can swing away from each other. When not in use, the floor slab component requires only a small amount of storage and transporting space since, after removing the floor slab, the frame legs of the lay-in frame can be folded closely against one another.
