The invention relates to devices for placing the pivot arm pressure roller pageviews, which can be used on bessoltseva spinning equipment, such as spinning machines.

In the spinning apparatus throughout its length mounted release tab line riptionlow containing for each pageviews corrugated bedside table and pressed her rotating pressure roller, which is mounted on a swinging lever mounted on passing through the entire length of the spinnerets common fixed axis (SU 456058 And 25.04.1975).

A disadvantage of the known device consists in the complexity of the compact and suitable layout of the apparatus and having a discharge sprocket chain in the transmission of each issue release line riptionlow.

It is known a device for placing the pivot arm pressure roller pageviews containing installed between the posts and the supporting roller lever with rotating pressure roller axis and helical spring (LIKUCHEVA Z.A. Spinning and twisting machines, Moscow, Light and food industries, 1984, pagination 126-127).

The objective of the invention is to provide a device for placing the pivot arm pressure roller pageviews providing technical result consists in increasing production which include qualities spinning apparatus and improving the conditions of their operation.

This technical result in the device to accommodate the pivot arm pressure roller pageviews containing installed between the posts and the supporting roller lever with rotating pressure roller axis and a helical spring, is achieved by the fact that the axis fixedly mounted between flat racks attached by bolt lugs to a vertically placed base to base, and a spiral spring mounted on the axis and its ends are fixed on the rotary arm and on one of the racks.

Flat racks are rectangular areas, turning into the bolt tabs.

The axis is made of stepped and has a base end sections terminating in a threaded parts.

Flat racks are the base of the recess corresponding to the profile of the base end sections fixed axis, and holes to accommodate its threaded parts.

Posted by end of the spring strut has a cylindrical hole to accommodate the straight end of the spring.

In the bore of the hub of the rotary lever on the inner surface side of the location of the spring is cylindrical recess to accommodate the straight end of the spring.

The device illustrated by the drawings, in which figure 1 shows a section a-a fixture in figure 2; figure 2 - a view B in figure 1; figure 3 - individuals who other fixed axis pivot arm; figure 4 is a view In figure 3; figure 5 is a coiled spring; figure 6 - cross section G-g of figure 1; figure 7 - cross section d-D in figure 1.

The device includes a flat racks 1 and 2, with the bolt lugs 16 and 17, which is a continuation of rectangles, which stands 1 and 2 are inserted into the corresponding holes of the base vertically installed base (not shown).

Due to the threaded sections at the bolt lugs 16 and 17 of the rack 1 and 2 nuts (not shown) attached to the vertical base to base.

Between the posts 1 and 2 posted speed axis 3. On having a smaller diameter d1plot axis 3 of the hub 5 has a rotary lever 4 with a rotating pressure roller 13, is placed on the speed axis 14 (Fig 1 and 2).

On having a larger diameter d2plot axis 3 in the appropriate diameter of the cylindrical section of the hub 5 of the rotary lever 4 is mounted a spring rectilinear ends of which are fixed in a cylindrical recess 7 in the hub 5 and the hole 8 hours 2 (1, 6 and 7).

End of part 9 and 10 axis 3 made in the form of rectangles, oval, turning in the ends in the threaded part 18 and 19 (figure 3, 4 and 6).

Construction and mounting of the placed on the speed axis 14 of the rotating pressure roller 13 in the device are not considered.

Flat racks 1 and 2 are basic to the deepe the tion, the appropriate shape and size of the base end parts 9 and 10 of axis 3 and exclude its rotation (figure 1 and 6).

When assembling the device in the hub 5 of the rotary lever 4 section with diameter d1insert the axle 3. On the plot axis 3 and has a diameter of d2and corresponding in diameter to the bore of the hub 5 is inserted into the coiled spring 6, one end of which is placed in a cylindrical recess 7 of the hub 5 of the rotary lever 4 (Fig 1, 2 and 7).

On the end part 10 of the axis 3 is set to 1 hour (figure 1 and 3), and on the end part 9 hour set 2 with simultaneous placement in her hole 8 and the other end of the coil spring 6 (6). Following this, on the threaded part 18 and 19 of the axis 3 money appropriate nuts 11 and 12 (Fig.1-3).

Optimum compression of the uprights 1 and 2 on the axis 3, which provides free play-free rotation and longitudinal movement, optimum values of diameters d1axis 3 and the hub 5 of the rotary lever 4 and the optimal values of the size of axis 3 (figure 3) and size N (figure 1), where With a few more N.

The necessary clamping pressure roller 13 to the grooved table 15 release a couple of riptionlow is achieved by the elasticity of working for torsion coil spring, is received at an acceptable unwinding of the spring to achieve a desired clamping pressure roller for ribbed t is bocce.

In the process of riptionlow of pageviews device provides a constant pressure of the pressure roller to the corrugated nightstand. If necessary, the removal of the roller from corrugated tables manually by a raising and a slight turning up of the lever.

The lubrication device is carried out during Assembly and inspections.

SUBSTANCE: feeding frame for textile machine has binders mounted on columns and equipped with hangers and brackets, spool holders placed on hangers, and guiding rollers. Each of spool holders has rotary stop disposed at its lower end and adapted for holding spools in operating position and allowing spools to be removed and installed in zone at the level of operator's eyes without detachment of spool holders from frame hangers. Aperture of each hanger has size slightly greater than diameter of spool holder hook rod. Each hanger has rib allowing spool holder to be removed from hanger only upon turning thereof through angle of about 60° to hanger axis for preventing spontaneous falling of spool holder from hanger. Guiding rollers have flange made in the form of continuous conical disk arranged at its one side and flange made in the form of four fingers arranged at its other side. Such construction imparts strength to rollers and allows rollers to be readily cleaned from filaments adhered thereto. Frame units are mounted on two columns transverse thereto. Attachments for all frame units are made adjustable to provide for mounting of spools of different sizes.
