Abstract

The invention relates to a method by means of which on an industrial scale a Hatstumpen (9) made of wool felt by the meter (1) can be produced. According to the method, individual wool felt pieces (3) are cut out of a long wool felt web (1), each formed into a wool felt cone (4) and fixed in this shape by means of a seam (5). Such a wool felt cone (4) is rolled at elevated temperatures and a predetermined humidity, whereby the wool felt cone (4) shrinks and the seam (5) becomes invisible. It is then produced by smoothing and shaping of the capstans (9).

Description

The invention relates to a method by which Hutstumpen can be made of wool felt by the meter.

Wool felt hats and methods for their production are known in principle. Here, a distinction can be made in processes in which a hat is made from a single piece of wool, and methods in which from yard goods, d. H. long wool felt, a variety of hats is made.

DE 137410 A describes a machine for molding Wollfilzhüten, wherein a held down by a press ring wool felt piece by means of a introduced from below wood shape and from above over the wood shape to be stuffed, steam-heated bell shape is pulled down to form a Hutstumpens. Although a hat stump made using this machine is in one piece, the wool felt is pulled apart unevenly during the molding process, resulting in unsightly, heavily thinned areas.

In DE 1340196 U there is disclosed a method for making a wool felt hat in which two wool felt parts, a tube part and a head part, are sewn together, the seam subsequently being made invisible by suitable whisking or roughening on the outside of the hat bone.

A disadvantage of this o. G. Process is the discontinuous production process, whereby only individual wool pieces are used for Hutstumpenherstellung.

Cost-effective in the production is the use of meterware. DE 82926 A describes a method and a device for the production of Hatstumpen, wherein a wool felt web in the required (controllable) width, but produced in continuous length and the Konuskrempel is presented so that on the same for each double breasts required Florlängen means of a bell apparatus (not by fleece interruption).

A disadvantage of the production of wool felt hat stumps using wool felt webs from the prior art is a seam clearly visible after the necessary sewing of the individual wool felt pieces to the hat stump.

Also known are fulling mills, such as hammer rolls, for use in the manufacture of hair and wool stockings, as well as berets and other knitted articles. The hammer mill works on the well-known stamping principle, the Walkteffekt is very even under the influence of moisture, heat and the pressure of the hammer joints and equalizing effect on any irregularities in the felt.

For industrial production, however, both the use of sold by the meter and the production of a hat made of only one wool felt piece is desirable.

The invention has for its object to provide a method by which Hutstumpen using a long (almost endless) wool felt webs, d. H. Wool felt by the meter, can be made from only one Wollfilzstück, with virtually no seam should be visible on the finished product. The method should also allow cost-effective production on an industrial scale with little time and effort.

The solution of this task is carried out according to claim 1; expedient embodiments of the invention can be found in the subclaims.

According to the invention, a method is provided, which is based on the Verwalken one of a (endlessly long) wool felt and cut into a cone sewn wool felt piece.

As used herein, the term "walk" describes a process wherein a source, e.g. As a wool felt, with a stamping device, such as a hammer roll, is acted upon for a predetermined period of time on the entire surface by pushing, squeezing and pounding, wherein a Einwirkbereich a single stamping operation may be smaller than the entire surface of the starting material.

The term "cone" is generally understood to mean a three-dimensional body known from geometry with a surface of revolution which is formed by the rotation of an arbitrary curve about an axis.

• – Ausschneiden eines einzelnen, d. h. einstückigen, Wollfilzstückes aus einer langen Wollfilzbahn unter Zuhilfenahme einer Schnittschablone, wobei das Ausschneiden automatisiert erfolgt (beispielsweise durch Ausstanzen);
• – Formen dieses einstückigen Wollfilzstückes zu einem Wollfilzkonus, d. h. einer konusförmigen Hutstumpen-Vorform, wobei Bereiche des Wollfilzstückes entlang einer Fügenaht überlappen;
• – Kraftschlüssiges Verbinden der beiden an der Fügenaht überlappenden Bereiche des Wollfilzstückes durch Vernähen mit einem Wollfaden unter Ausbildung einer Naht, die in diesem Stadium der Fertigung sichtbar sein kann;
• – Walken des Wollfilzkonus bei erhöhter Temperatur (d. h. bei einer Temperatur oberhalb der Raumtemperatur) und – durch Zugabe von einer Walkflüssigkeit – bei einer vorgegebenen Feuchtigkeit; und
• – Glätten und Ausformen des Hutstumpens.

The method according to the invention for producing a hat pile of wool felt by the meter comprises the following steps:

• - Cutting a single, ie one piece, wool felt piece from a long wool felt web with the aid of a cutting template, the cutting is done automatically (for example by punching);
• - Forms this one-piece wool felt piece to a wool felt cone, ie a cone-shaped Hatstump preform, wherein portions of the wool felt piece overlap along a joint seam;
• - Frictionally connecting the two overlapping on the joint seam portions of the wool felt piece by sewing with a wool thread to form a seam that may be visible at this stage of manufacturing;
• - Walken the wool felt cone at elevated temperature (ie at a temperature above room temperature) and - by adding a flexing liquid - at a given humidity; and
• - Smoothing and forming the Hutstumpens.

Optionally, it may be provided that the capstumps, z. B. following o.g. Steps to color, for example by immersion in a dyebath. But it can also be provided to use a staggered with a color flexing liquid to perform the Walkens, so that the color can penetrate during the Walkens in the wool felt and can connect to the same permanently, d. h., the Hatstumpen is dyed simultaneously with the walking.

The walking can be carried out, for example, with a hammer mill known from the prior art. Here, the wool felt in tubs by wood hammers, which are driven by a shaft and a shaft pivot mounted on the rocker, driven. For a good flexing work, the correct ratio of fill weight to volume of the hammer mill is of great importance. In addition, the moisture content and temperature of the stumps during the hammer walk are significant factors influencing the later quality of the hat pumps.

It is also possible to use a pilgrim step roll mill or a so-called multiroller, each of which has rollers for walking. Here the felt is rolled flat and then rolled. The walkwheels do not rotate continuously but swing forward and backward, with the backward vibration being less than the forward vibration.

The duration of the walk depends on the type, thickness and quality of the wool felt, the size of the hat stumps and the walk intensity. It has been found that by rolling wool felt pieces, they become smaller, i.e., smaller. H. shrink in size. The duration of the Walkens will thus also be dependent on the desired final size of Hutstumpen, as this shrinkage process is also observed in the wool felt hat pumps.

The flexing fluid used during the moisturizing walk may be pure water, an alkaline liquor or even an acid. Furthermore, it can be provided to put the Walklfüssigkeit with additives such. As alumina or dye, be added water.

The method according to the invention has the advantage that the seam, which is usually clearly visible in wool felt hats, becomes completely invisible on the hat stump. By means of the method step of the waving, the threads of the fabric, in particular the wool thread used for sewing on the joining seam, are completely hidden.

The method also offers the advantage of an industrially possible production with little technical and time expenditure by z. B. wool felt by the meter is used.

The method can be used for the production of Hatstumpen with any shape, in particular, only a single wool felt piece is used to form the Hutstumpens.

By choosing the cutting template, the shape of the hat trench can be chosen freely. Thus, z. B. conical, frustoconical, dome-shaped or hemispherical Hutstumpen produced.

According to one embodiment variant, the step "smoothing and shaping" is also carried out at an elevated temperature and a predetermined moisture of the hatch. It can also be provided that the still moist hat-stump dried in the course of this process step, d. H. the moisture is removed.

The method according to the invention may further be designed in such a way that the hat size of the hat stump to be produced, i. H. the diameter of the hat-stump adapted to the head size of the future hat-wearer, to be adjusted by the duration of the waving process. Thus Hatstumpen for small head sizes are gewälkt longer than Hutstumpen for large head sizes, the minimum Walk duration is selected such that even with the shorter Walk duration formed when sewing the Wollfilzstückes seam is invisible.

The advantage here is that for each hat size the same template can be used to cut out the wool felt piece from the wool felt by the meter, the hat size being determined solely by the flexing time.

The invention will be explained in more detail below with reference to a figure. Here, in a schematic representation, the figure shows the method in selected method steps.

From the piece of furniture unwound from a roll 1 is by means of the punching device 2 the wool felt piece 3 cut out. Then this wool felt piece 3 to the wool felt cone 4 sewn together, with the seam 5 is trained. This wool felt cone 4 is in the tub 8th with the addition of the Walk liquid 7 with the hammerwalke 6 fulled. After drying and straightening the rolled wool felt cone 4 The result is a seamless hat-stump 9 ,
