DESCRIPTION:
BRIEF SUMMARY
The invention relates to a napping machine, in particular a card wire napping machine, for napping at least one web of textile goods, wherein napping rollers, which are arranged in a planetary manner and driven, are seated in a driven main cylinder arrangement, sometimes referred to as a swift, which is seated in the machine frame and is cylinder-shaped in principle.
In a napping machine of this type described in DD-PS 213 249, the main cylinder is embodied by at least two round anchor plates which support the napping rollers. These round anchor plates arranged on the front or respectively the longitudinal ends of the main cylinder are each seated on at least three rollers. At least one stripping roller, arranged in a dust collecting device, should be provided inside the main cylinder. By means of this design and seating of the main cylinder it is achieved that space is created on the longitudinal sides of the main cylinder for inserting or respectively arranging an aspiration and stripping device on the interior of the main cylinder. In contrast to customary machines, such as described in DE-AS 11 37 713, the main cylinder known from DD-PS is not seated by means of spokes or the like on a main cylinder shaft, but on the rollers positioned on the inside of the main cylinder circumference or respectively of circumferences of the round anchor plates.
By means of the stripping and aspiration of the main cylinder in the main cylinder interior provided by the above mentioned DD-PS 213 249 it is achieved that, in contrast to napping machines, whose napping rollers are stripped on the outside of the main cylinder, practically the entire outer (i.e. located opposite the stripping means) circumference of the main cylinder is available for the napping process and the efficiency of the machine is correspondingly increased. However, the seating of the main cylinder on the two round anchor plates by means of the rollers is problematic. Because of the known three- or multi-point seating of the main cylinder or respectively of the round anchor plates, the noise generation of the machine becomes so great that separate sound-deadening means are required. Aside from the fact that the outlay for sound-deadening is very large, the noise generated by the machine also indicates considerable wear, so that the service life of the seating of the main cylinder or respectively its round anchor plates on the rollers is very limited.
It is the object of the invention to create a main cylinder seating which also allows a lateral access to the main cylinder interior, but assures quiet running with little noise generation and low wear.
The attainment of the object in accordance with the invention in connection with the napping machine of the type mentioned at the outset lies in that the main cylinder is received at the two longitudinal circumferential edges in respectively one ring-shaped ball bearing, one of whose ball bearing shells is a part of the main cylinder and whose other ball bearing shell is a part of the machine frame.
Accordingly, the main cylinder is constituted by elements fastened on the one ball bearing shell, which assure a reception for the napping roller seating. Preferably the exterior ball bearing shell fastened on the machine frame encloses the inner ball bearing shell fastened on the main cylinder, so that the main cylinder is actually only constituted by the elements (for the napping roller seating) fastened on the appropriate inner races of the ball bearings.
Preferably the ball bearing consisting of the two ball bearing shells including balls, rollers or the like should be designed to be ring-shaped and be of a size corresponding to the circumference of the main cylinder. In any case, the ball bearing race should have a diameter which is a multiple of former main cylinder seatings.
In accordance with the further invention, a main cylinder drive is provided on the inside of the main cylinder, which directly acts on the main cylinder, possibly on the inner ball bearing shell. Conventional driving means, for examp
