PATENT OFFICE.

For the partial reinforcement of hose ware, such as B. the high heel c, Fig. 1, and the sole of the foot d , as indicated in Fig. 2 in front view, Fig. 3 in cross section and Fig. 4 in outline, a Lamb's knitting machine with four locks is used. Each lock system consists of two lifting triangles f and J ₁ , Fig. 7, and three lowering triangles g, g _x and g ₂ . . The former can be alternately pushed up by some known mechanism and thereby put on their toes in such a way that only the right-hand or only the left-hand lock of a system lifts the needles or lowers.

Each lock system has a driver h or Λj, Fig..3, called cannon, for moving the thread guide. These cannons are arranged in such a way that thread guide k, FIGS. 8 and 9, is taken along as soon as the latter is above the rear left lock, whereas thread guide A: when it is above the front right lock. Both thread guides k and k ₁ therefore maintain a distance which is approximately equal to that of the two lifting triangles / and / _x ; consequently they do not pass by side by side.

A thread guide is arranged on each side of the slide and each serves to guide a main thread χ and y, FIGS. 2 and 3, which form the unreinforced goods. A row of stitches is knitted at the same time on the front as well as on the rear fontur with each stroke of the slide, which are connected by a crosshair at the ends, due to the alternating feeding of threads χ and y to the front or rear row of needles. In FIG. 10, the thread connection at this crossing point is indicated, as it appears when the goods are torn apart on the outside of the latter. The wales p _i p ₂ p ₃ hang on the needles of the front bed and those q _x q. ₂ q _& on the needles of the rear bed. At the same time, the thread χ on one row of needles forms stitches p, p ₂ p ₃ and the thread on the other forms stitches q ₁ q <> q ₃ . After a toboggan tour, the threads swap the rows of needles, which results in the formation of the crosshairs.

To reinforce the goods, a third thread ^, with the aid of two catch thread guides m and Ot ₁ , Fig. 4, 8 and 9, is fed. Each catch thread guide is connected to the outlet tube /, FIGS. 5 and 6 (front view and cross section), of the main thread guide and is formed from an angularly bent sheet metal. The two catch thread guides m and Wi ₁ face their open side.

The method by which the reinforcement thread, for example, always only from the rear row of needles is processed, regardless of whether the locks are to the right or move left over the rows of needles is the following:

As is assumed in FIG. 4, the carriage may be moved to the left.

It works (see Fig. 8) first the front left lock with the rear thread guide k and then the rear right lock with the front thread guide Ar ₁ . The reinforcement thread ^, which goes from the last stitch up to the thread holder (the latter, because it is not

borrowed, not specified) is running, is released by the preceding catch thread guide m as the carriage moves further, grasped by the trailing Mi1 and thereby fed to the rear row of needles. If the carriage now turns around and makes a tour to the right, the lock positions change and work (see Fig. 9) first the front right lock with the front thread guide Zc1 and then the rear left lock with the rear thread guide k. The reinforcement thread, which was carried along by the fishing thread guide mx during the previous carriage movement, leaves this and is grasped by the other following fishing thread guide and fed back to the rear row of needles. The reinforcement thread% is therefore only ever fed to the rear row of needles and the fabric hose is reinforced by half. The mode of operation, however, remains the same if the reinforcing thread is allowed to work from the front row of needles, only one has to reverse the mutual change of the locks that are active. According to this, z. B. on the toboggan tour to the left (see Fig. 8) to engage the two dotted locks. The thread guide position remains the same. In Fig. 11, the thread connection, produced by the threads χ and y ^ as it is shown on the inner surface of the goods, is shown and the reinforcing thread% is also drawn. Sponsorship τ claims: 1. Process for the production of partially reinforced smooth tubular goods, consisting of that the reinforcing thread is always alternating on the same half of the fabric processed with one of two main threads, which serve at the same time to form the piece of goods, but with each one Slide stroke with respect to the rows of needles are interchanged, so that both halves of the goods connected by simple crossing at the reversal points. 2. A Lamb'sehe knitting machine for carrying out the process identified under 1., in which the reinforcing thread is always fed to the same row of needles by two catch thread guides (in and mj, which move with the main thread guides (k and kj and turn their open side) The fact that the four locks used work offset against each other and change after each slide stroke, whereby the previous active lock always knits the main thread of the respective first standing thread guide, i.e. the same lock system exchanges the thread guide after each slide stroke, whereby the reinforcing thread of the following catch thread guide catches and that row of needles is fed which, according to the closed position
occurs. last in action 1 sheet of drawings.
