Definitions
- This invention relates to a device for weighting the press rollers of draw frames for spinning machines, and has for its object to provide for easy adjustability, variation or relief of the top roller pressure at some or all gripping points from a central station while eliminating the vibrations resulting from the use of weights and lever weighting or the different tensional stresses in case spring elements are employed.
- the invention overcomes these defects by employing a single pneumatic or hydraulic means subjected to regulatable pressure for weighting the top rollers at some or all points of a machine side.
- the use of hydraulic or pneumatic weighting means prevents the effects of vibration and obviates the necessity of providing bothersome relieving means, since the roller pressure is controlled by reducing or abolishing the hydraulic or pneumatic pressure itself.
- a considerable saving in material and thereby a reduction of initial cost and of the weight of the machine are effected, apart from the fact that the pressure can be uniformly distributed over the entire machine in a simple and convenient manner.
- Machines of this type can, moreover, be installed much more easily in buildings of lighter construction.
- the principal advantage is that the pressure can be readily varied throughout the machine and adapted to spinning conditions.
- the device according to the invention is preferably constructed by introducing into a tube a hose subjected to pneumatic or hydraulic pressure and acting upon pressure plates provided within the tube and connected by levers with the weighting saddles.
- the tube may serve also as support for the top roller holders.
- Each pressure plate possesses a protruding portion projecting from the tube and resting in a notch in the slotted wall. On its other end, the protruding portion of the plate supports a weight lever and swings it about the slotted wall serving as fulcrum.
- the hose and pressure plates may be replaced by pneumatically or hydraulically controlled pistons.
- Figure 1 is a section on the line I-I of Fig. 2 which shows the draw frame of a spinning machine and shows in side elevation, and partly in section, the means provided for the transmission of pressure;
- Fig. 2 is a plan of the draw frame.
- a support 2 having the form of a tube for the top roller holders 3 contains a hose 4 extending as required over an entire machine side or a plurality of pressure points. At each of these points the tube 2 is provided with slots 5 through which pressure plates 6 are introduced and bear against the hose 4. The pressure plates 6 are fitted below with an eye 1 and rest with a notch 8 on one side of the slots 5 of the tube 2.
- a weight lever 9 is secured which acts in front upon the saddle l0 resting with two notches on the top rollers H, I2.
- Into the end of the tube 2 enters a pressure piping l3 connected with the hose 4 by a valve M.
- the device functions as follows:
- the hose 4 is subjected to pressure by the piping l3 with the aid of the valve M, which pressure is adapted to the pressure to be exerted upon the top rollers ll, l2.
- the pressure spreads uniformly throughout the hose 4 and is transmitted to the pressure plates 6 each of which swings about the notch 8, acting as fulcrum, in counterclockwise direction and takes along the eye I and the weight lever 9, so that pressure is transmitted to the saddle I0 and thus to the top rollers l I, I2.
- the tube 2 for the reception of the hose 4 and of the abutting plates 6 need not always be centrally arranged inside the support for the top rollers, but may also be disposed so as to extend beside and along it. This latter arrangement is particularly suited for installing the device in already existing drawing frames.
- a weighting device for the top rollers of draw frames in spinning machines comprising a slotted support for the top roller holders, a hose in said support, a pressure piping connected with said support, a valve connecting said piping with said hose, pressure plates introduced through the slots of said support and bearing against said hose, said pressure plates having a, notched projection engaging through a slot of said support and resting with its notch on one side of the slot, an eye formed in said pressure plates and a weight lever secured in said eye and acting in front upon the saddle of the frame resting on the top rollers and thus subjecting the top rollers to pressure variable as to spinning conditions.
- a device in which the support for the top roller holders is formed as a tube.
