Description
Ralph A. Graf, 8807 Freienbach / Switzerland Combing Device for a Circular Comb and Method for the Manufacture of the Combing Device ------------------------------------------------------The invention relates to a combing device for a combing machine, having at least one circular comb and at least one top comb and having a number of comb teeth serving to engage in a fiber fleece and arranged side by side in a direction that is approximately vertical to the direction of combing.
The combing machine serves to refine yams manufactured from textile fibers. In the manufacture of yams, it is typically arranged between the carding and the stretching station. The main tasks of the combing machine consist of the elimination of short fibers from the card slivers produced by the carding station, i. e. the improvement of the stack of the raw fiber material as well as the improvement of the paralielization of the individual fibers of the fiber fleece supplied by the carding station in the form of the card sliver. As a secondary effect, further cleaning of the fiber fleece is achieved in the combing machine by the elimination of neps and seed particles. To achieve the improvements of the fiber fleece described above, a fiber tuft of the fiber fleece, which is fed from a supply cylinder and held by means of a gripper, is combed through by a circular comb in the combing machine, which rotates about a fixed axis; said fiber tuft is then soldered with an already combed combing fleece and is then torn off of the fiber fleece yet to be combed due to the engagement of a top comb in the tuft which has been combed by the circular comb and the simultaneous removal of the combing fleece from the supply cylinder. The desired improvement of the parallelism of the individual fibers of the fiber fleece as well as the improvement of thd stack by means of elimination of short fibers is effected by the interaction of the circular comb and the top comb.

The desired improvement of the parallelism of the individual fibers of the fiber fleece as well as the improvement of thd stack by means of elimination of short fibers is effected by the interaction of the circular comb and the top comb.
The top comb of conventional combing machines is typically composed of a support element in the form of a sheet metal strip and comb teeth soldered thereto in the form of flat needles. It has been shown that, especially when the combing machine is operated at high operating speeds and when such top combs are used, it is impossible to achieve a parallelization of the individual fibers of the fiber fleece that satisfies the requirements of high quality yarns, while at the same time heavy soiling of the top comb is observed, which makes frequent cleaning necessary. In order to eliminate this deficiency, DE 195 31 proposes a further development of conventional top combs, characterized by the comb teeth of the top comb as well as the comb teeth of the circular comb having the form of saw tooth wire sections with, respectively, at least one saw tooth exhibiting tooth flanks extending essentially parallel to the direction of combing and a tooth face extending vertically thereto. Here, the saw tooth wire sections used for the manufacture of the top comb as well as the saw tooth wire sections used for the manufacture of the circular tooth may consist, respectively, of a base and a reed joined thereto and exhibiting the at least one saw tooth, with the dimensions of the base being greater in a direction extending essentially vertically to the direction of combing than the dimensions of the reed in this direction, so as to provide the combing spaces enabling the passage of the fibers through the respective comb elements during the combing process.
For the manufacture of such combing devices, a wire-shaped basic raw material is first subjected to a cold rolling process in order to create a wire profile forming the base area and the reed area of the saw tooth wire sections. In a next manufacturing step, the saw teeth are extracted from the profile wire using a punching process. From the saw tooth wire thus obtained, saw tooth wire sections are cut off to such a length that is required for the manufacture of a top comb or a circular comb. The saw tooth wire sections are then combined into bundles and attached on a suitable support element. Following the extraction of the saw teeth from the reed section of the profile wire, the saw teeth can be subjected to a hardening process, such as, e. g., a laser or flame hardening process.

The saw tooth wire sections are then combined into bundles and attached on a suitable support element. Following the extraction of the saw teeth from the reed section of the profile wire, the saw teeth can be subjected to a hardening process, such as, e. g., a laser or flame hardening process.
As it can be gathered from the above explanation of conventional combing devices for top comb machines, their manufacture involves significant costs.
In view of these technical problems, the invention is based on the technical problem of providing a combing device for combing machines, with said combing device being especially easy to manufacture and with said combing device allowing the production of a high quality carded and combed (top) sliver or a high quality combing machine ribbon, using high machine running times and high operating speeds, as well as providing a method for the manufacture of such combing devices.
According to the invention, this problem is solved by means of a further development of the conventional combing devices, with said further development being essentially characterized in that the combing device exhibits at least one comb element with at least two, preferably three or more comb teeth made in one piece and arranged side by side in the direction extending vertically to the direction of combing.
This invention is based on the insight that problems encountered in the manufacture of conventional combing devices for combing machines are primarily due to the fact that their comb teeth are formed by means of a multitude of individual parts to be arranged side by side, such as, e. g., saw tooth wire sections, with the additional requirement that these individual parts have to be manufactured beforehand using a required manufacturing process (cold rolling, punching, hardening).
These problems are eliminated in the manufacture of the combing device in accordance with the invention because two, three or more (if necessary 20, 30 or more) of the comb teeth arranged side by side in the direction extending vertically to the direction of combing are combined into a comb element made in one piece such that the process of bundling and attaching of the comb teeth to a support element can be significantly simpiified. In addition, it is possible to produce the comb elements of combing devices in accordance with the invention in a particularly simple way because the preparatory activities to obtain the profile wire are eliminated and thus a basic raw material which exhibits the desired material properties without having to undergo an additional hardening process can be used for the manufacture of the comb eiements.
As can be gathered from the explanations regarding conventional combing machines, it has been shown to be particularly advantageous if at least one of the comb teeth has a saw tooth-shaped design with two tooth flanks extending parallel to the direction of combing and a tooth face connecting the tooth flanks and extending approximateiy vertically thereto, with the transitions between the tooth flanks and tooth face possibly being rounded.

With conventional combing devices, the fixing of the comb teeth is achieved via special fastening elements to which the comb teeth have to be attached. With the comb elements of combing devices according to the invention, it is also possible for the fastening area designed for the attachment of the comb element to the combing machine to be made in one piece with the comb teeth.
Especially when using combing devices in accordance with the invention in the form of circular combs for a combing machine, but also when using combing devices in accordance with the invention in the form of top combs for a combing machine, it has been shown to be advantageous, in order to obtain an especially desirable combing effect, for the comb element to exhibit at least two, preferably three or more comb teeth arranged in series. When using combing devices in accordance with the invention in the form of top combs, the tips of the comb teeth arranged side by side in the direction extending vertically to the direction of combing are expeditiously arranged approximately on a straight line extending vertically to the direction of combing. The tips of the comb teeth arranged in series in the direction of combing are preferably arranged, when using combing devices in accordance with the invention in the form of circular combs, approximately on a circular arc, the center of which falls on the fixed axis rotated about by the circular comb.
To manufacture the combing devices in accordance with the invention, it is no longer necessary to first subject the base raw material to a cold rolling process and then a punching process. For this reason, the comb elements of combing devices in accordance with the invention may be made at least in part from high-alloyed steel, in particular stainless chrome nickel steel, the cold forming properties of which would no longer be sufficient for the manufacture of profile wires.
As can be gathered from the explanations regarding combing devices in accordance with the invention, a comb element suitable for its manufacture is essentially characterized in that it exhibits at least two, preferably three or more (if necessary 20, 30 or more) comb teeth made in one piece and arranged side by side in the direction extending vertically to the direction of combing.
A top comb according to the invention, obtained by using respective comb elements, is essentially characterized in that it exhibits two, three or more comb teeth made in one piece, the tooth tips of which are arranged on a straight line extending approximately vertically to the direction of combing.

A top comb according to the invention, obtained by using respective comb elements, is essentially characterized in that it exhibits two, three or more comb teeth made in one piece, the tooth tips of which are arranged on a straight line extending approximately vertically to the direction of combing.
A circular comb manufactured by using comb elements in accordance with the invention comprises both two, three or more comb teeth made in one piece and arranged side by side in a direction extending vertically to the direction of combing, as well as two, three or more comb teeth made in one piece and arranged in series in the direction of combing. In this context, it is possible, both for the manufacture of top combs in accordance with the invention and the manufacture of circular combs in accordance with the invention, for two, three or more comb elements in accordance with the invention to be arranged side by side in a direction extending vertically to the direction of combing, and with it also being possible - especially for the manufacture of circular combs in accordance with the invention - to arrange two, three or more comb elements in series in the direction of combing.
A method in accordance with the invention for the manufacture of a comb element in accordance with the invention for a combing device in accordance with the invention is essentially characterized in that, in a first processing step, starting with, for example, an approximately cuboid raw material block, specifically made from high-alloyed steel, such as, e. g., chrome nickel steel, the slots separating the individual comb teeth from each other in the direction extending vertically to the direction of combing are formed in the raw material and then, in a second processing step, the form of the comb teeth is removed from the raw material block in an aspect that is vertical to the direction of combing, while a connecting area connecting the comb teeth with each other in the direction extending vertically to the direction of combing as well as the fastening area of the raw material block, serving to fasten the comb element to the combing machine, are being preserved.
For the purpose of an efficient manufacture of comb elements and combing devices in accordance with the invention, it has been shown to be particularly advantageous to form two, three or more slots simultaneously in the first processing step. An efficient manufacture of comb elements or combing devices in accordance with the invention may be ensured, while ensuring the required high manufacturing precision, if the first and/or second processing step is carried out by spark erosion machining or spark erosion depth machining, with it being possible to use a multi machining head for the simultaneous formation of two, three or more slots in the raw material block and /or the simuitaneous removal of two, three or more saw teeth arranged in series in the direction of combing.

It is possible to further accelerate the manufacturing method in accordance with the invention by processing the raw material block in the second processing step from two opposite directions, respectively extending vertical to the direction of combing.
In the following, the invention is explained by reference to the drawing, which is expressly referred to with respect to all details that are essential to the invention and details that were not elaborated on in detail in the description. The only figure of the drawing schematically illustrates a method in accordance with the invention for the manufacture of comb elements in accordance with the invention, which are suitable for the manufacture of top combs in accordance with the invention. In accordance with the drawing, a raw material block, e. g. made from stainless high-alloyed steel, such as e. g. chrome nickel steel, is used as a basic raw material for the manufacturing process. The width b of this raw material block may be up to 300 mm and the height h of the raw material may be 5 to 15 cm, specifically 10 cm. The depth t of the raw material block may be 1 to 10 mm, specifically 3 to 5 mm. In the manufacturing process shown schematically in the drawing, the slots 12 are removed from the raw material block 10 in a first processing step via spark erosion machining using a multi machining head 20, with said slots 12 separating the comb teeth from each other in a direction P
extending vertically to the direction of combing. In this process, three slots 12 are simultaneously created by means of the multi machining head 20. In other embodiments of the invention, four or more slots 12 or 2 or fewer slots 12 may be produced simultaneously. In a second processing step, profiles 50 are simultaneously removed in an aspect directed vertically to the direction of combing, by means of machining heads 30 and 40, from the raw material block 10, from two opposite directions respectively extending vertically to the direction of combing. These profiles may exhibit, underneath the slots 12, a fastening area 54 connecting the combing teeth with each other, as well as saw teeth shaped combing teeth 52.
In both processing steps, spark erosion processes may be used. In contrast to conventional processes for the manufacture of combing devices for combing machines, such processes allow for the manufacture of comb teeth 52 of any desired form, specifically any face form and teeth or tooth flanks of any profile. In this process, the flanks of the tooth-shaped teeth 52 may converge, for example, in sections, symmetrically in the direction of the tooth tips with respect to a plane extending vertically to the direction P. The invention is not restricted to the embodiment explained by reference to the drawing. Instead, the manufacture of circular comb sets by means of processes in accordance with the invention is also contemplated.
