- This invention is directed in part to solving the problems of constructing a spinning machine of the type mentioned above, with the use of the conventional bearing and drive elements, in such a manner that no excess running noises occur during operation.
- the present invention contemplates accommodating the turbine shafts, including their. bearings and drive means, in a closed duct extending in the longitudinal direction of the spinning machine, perpendicular to the turbine shaft axes. With this closed duct construction, the parts which cause running noises are well encapsulated so that the running noises are noticeable on the outside of the duct only to a minor extent. Also, by the arrangement of the bearing and drive elements of the spinning turbines in a duct or tunnel, an optically pleasing impression of the entire spinning machine is obtained, since in this way a smooth exterior and compact mode of construction is made possible.
- the present invention further contemplates a further development of the duct construction and the advantages thereof to fashion a spinning machine so that the manufacturing costs are reduced.
- This further development includes the provision of a duct which is composed of several series-disposed elements which are preferably constructed as supporting base members; each of these base members being fashioned as receiving and mounting means for components of several adjacent spinning units.
- the casing of the drive and mounting means fashioned as a duct, fulfills additional functions in conjunction with the noise attenuation.
- the duct walls surrounding the turbine drive mechanism not only serve'for noise attenuation, but
- the present invention contemplates producingthe spinning machine in a sectional mode of construction, i.e., to subdivide'the spinning machine into sections of prefabricated components andthen to assemble these sections into the complete spinning machine.
- This sectional manufacturing or construction mode permits a more advantageous production and, very importantly, a more advantageous machining of the individual components with consequent increased accuracy. Also, the
- the present invention further contemplates an embodiment including the provision that the duct has a rectangular cross-section, wherein the base or main member, which is of a U-shape or of an angular configuration, forms at least the bottom and the rear wall, whereas the front wall and/or the ceiling are fashioned as a one-piece or multipartite cover or lid.
- the construction ensures a very stable arrangement, while simultaneously assuring ready accessibility to all assemblies contained in the closed duct.
- the base or main member is fashioned integrally with the turbine housings of several spinning units.
- This mode of construction has the advantage that these base or main members are provided with a high dimensional stability by the special structure of one wall.
- a wall attached as a detachable lid on the base member, preferably on the front side constitutes a turbine housing common to several spinning units. This last mentioned embodiment affords the advantage that servicing is simplified, since the accessibility of a section is improved by removing the lid-like turbine housing.
- the present invention contemplates dividing the common turbine housing by preferably detachable inserts.
- detachable inserts it is possible in a simple manner to subdivide the common turbine housing into several individual chambers.
- inserts with varying inner diameters can be inserted in the turbine housing.
- the present invention further contemplates an advantageous embodiment utilizing an extruded profile part of aluminum or the like for making at least the base or main member of the duct.
- a profiled part can be manufactured rather inexpensively in the de sired sizes and with the required degrees of accuracy.
- the'advantage is attained that no difficulties are involved in producing even a profiled part of a complicated shape.
- the present invention further contemplates an advantageous embodiment utilizing a sheet metal profile for making at least the base member of the duct.
- a sheet metal profile can be of advantage particularly in case of lightweight spinning machines.
- the base members can readily be dimensioned so that the duct represents the essential supporting structure for the spinning machine
- another development of this invention provides that the duct composed ofthe basemembers serves as a supporting structure for feeding and opening devices associated with each spinning unit.
- the present invention contemplates that removable intermediate or connecting pieces are disposed betweenthe turbine housings and the feeding and opening devices fixedly arranged therebelow.
- the present invention further contemplates utilizing the duct in still another manner, by providing'the topside of the base members with mounting means for take-off rolls, pirns, or the like.
- the present invention contemplates the provision of one or more air conveying devices to produce an air flow or stream through the duct.
- This air flow or stream prevents the localized development of heat at any place along the duct, which localized heat is detrimental especially for grease-lubricated bearings and for the drive means, especially sets" of supporting rollers or friction wheels or the like. Since the measures of this invention make it possible to remove the thus-produced heat within the duct, a special advantage is attained additionally for the engine rooms within which the machines are operating, since the air conditioner of these rooms is not burdened by this additional evolution of heat.
- the present invention further contemplates another embodiment of the invention which provides that the bottom of the base member is equipped with mountings for a detachable profiled rail receiving the bearings and/or guide elements and/or drive and braking devices of several spinning units.

Thereby, a further wall of the duct executes an additional function, .while simultaneously advantages are attained from the viewpoints of manufacturing technique and functional operation resulting from a sectional mode of construction.
- the rear wall of the duct is provided, preferably on its outside, with an oil channel closed off by a detachable lid and wherein an adjustable guide plate is arranged for each spinning unit, respectively one tubine shaft contacting this plate.
- an adjustable guide plate is arranged for each spinning unit, respectively one tubine shaft contacting this plate.
- the present invention contemplates providing elastic filling pieces between the oil channels of the adjacent base members. These fillerelements can separate the individual oil channels from one another, or they can also merely seal these channels with respect to the outside, so that an oil channel extending'along the entire spinning machine is created.
