Braiding machine for the production of "■ knotless braided webs

The invention relates to a lace braiding machine for Manufacture of knotless braided net webs, whereby the manufacture of the net legs and the connection points between the Netzschenkein in one operation. · Depending on the setting of the machine, it is possible, mesh webs with different widths and. Number of stitches to produce "

The knotless braided nets that can be produced on this braiding machine with preferably four threads in the Net legs are known and constructed in such a way that two threads always turn to the right in each net leg cross eight-shaped and the other two threads each other always cross to the left, the intersection of the eight-shaped structures of one set of threads in the eyes of the eight-shaped structures of the other Set of threads. At the connection point, at least one set of threads passes or changes through the neighboring one Net leg.

A method and a device have also become known _f by means of which it is possible to machine the net legs and the connection points for the formation of loops in knotless braided nets. The production of the knotless braided net webs takes place on braiding machines, the running tracks of which are divided into individual courses working together in a pattern in the braiding tables.

■ '"■ ■■:' ■■■ - 2 - '■■■;'

The tracks are divided into eight-shaped intersecting individual passages, each of which forms a braided head for the production of a set leg. In every second braiding head the bobbins assume the same position, with the bobbins being displaced over part of a partial step compared to the neighboring braiding heads After braiding the Uetz legs, the switches between every second braiding head are opened until the connection point changes or changes the clapper is made. ⁿ \ e other p ren previously closed points between the lichen heads will be opened after the re-braiding of the agitation legs

With a self-contained circular stringing together of the career paths divided into individual courses arise tubular hate rag. Should net towels with solid edges are produced, so end braiding heads are required in this known arrangement Bobbin the general bobbin winding on normal braided heads adapt, a phase shift of the clapper must be carried out on the end braiding heads.

} To carry out this phase shift in the clapper position it is already known to provide bypass or evasive paths on the end braiding heads

The disadvantage of the arrangement of dinghies and evasive paths is that they are in addition to the normal There are braided heads, which makes the braiding table complicated at the edges * A subdivision of the braided hull for the production of net panels of different widths and numbers of meshes can not·

It is also known to insert the braiding point formed directly above the braiding heads into the upper one To relocate the center of the circular machine «The highly displaced braiding point for the connecting exchange the braided strands is a prerequisite for the production of nets with small mesh sizes. In such devices, similar to Japanese twist braiding machines, there is an inclined base plate arranged · The base plate has the shape of a cone, so that all drawn perpendicular to it Cut normals at a point on the central axis of the machine. Above the base plate is a parallel. " Arranged top plate, which is connected to the base plate via supports and also has the shape of a Cone jacket, the normals of which intersect at the same point on the central axis. In the top plate thread guides are provided, which are moved synchronously with the bobbin winding. The base plate and the top plate are in accordance with the network characteristics to be produced provided with the individual running or * braided tracks «Above the top plate with the thread guides Circular disks are arranged with separating cams between them.

To guide the braids can be in the top plate In addition, cams moved synchronously with the beater barrel D3W. program-controlled slats can be installed.

The disadvantage of the facilities described with inclined The base plate lies in the inclined base plate itself »

The clapper 8 (Fig, 3), which are guided by the impellers 15, which are arranged in two rows, assume the same position in every second braid head. This is necessary because otherwise when replacing the Clapper 8 between the braided heads a collision occurs. Would the clapper 8 according to the one described here Embodiment assume the same position in each braid head, so the exchange of the clapper would have to between the braided heads via Volkenborn's rotary | operator or via bypass railways. In Fig. 3 is a normal unit 4, a division unit 5 and the End unit shown on the left 6 · The first two units each have three braiding heads and one end unit one and a half braided heads on.

The control device 14 works on the principle of a jacquard machine with a punched card. The number of braids * in the leg is determined by the number of punch cards · The number of braids is a measure of the length of the leg. The control device 14 also controls the length of the penetration when braiding the connection point.

In order to achieve a connection between the legs of the net the clapper 8 is passed via the control switches 32 (Fig. 11, 12) from one braiding head to the adjacent braiding head.

The exchange process is triggered by the control unit 14 as soon as a certain net leg length is braided · Since the control unit 14 is rigidly connected to the braiding heads, the drive also takes place in the control unit 14. The movement of the control unit is synchronous with the I ¹ real process · Every rotation of an impeller 15 thus generates a scanning process on a jacquard card. The jacquard card "is moved on a kbent.

The slide 50 'on which the lever 51 is rotatably suspended takes the shift drum 52 with it during its horizontal sliding movement. As a result, the flap 53 is moved by a pin 33 and generates an electrical switch-on contact in the limit switch 54-. A circuit through which the pull magnets 56 (FIG. 15) are fed is closed via this switch 54.

The duration of the power supply is determined by the design of the switching drum 52. When the pull magnet 56 responds, the lever 57 is pivoted and releases the rotary wedge 58 so that a tension spring 59 from Rotary wedge 58 a connection between drive wheel 61 (Fig. 13Ji ^) and switching head 60 is made.

This rotary wedge coupling 87 is generated via a cam disk 64 a pivoting movement on a lever 88. In normal operation, the force curve takes place from a pinion 89 »that into the central drive wheel engages, via a V / elle 90 to a ratchet head 91 In the coupled state, the rotary movement generated by a gear 92 is transferred to the braid lifter 9; 10 (Fig. 16; 17) initiated, -ienn the lever 88 in the area of the ratchet head 91 is pivoted the non-positive connection is canceled by dissolving the swivel joint connection

during this idle time, the lever 88 takes place a pivoting movement in its starting position, so that there is nothing to prevent the locking of the rotary wedge connection in the ratchet head 91 after one revolution.

This interruption of the drive connection creates the rhythmic offset and the reallocation of the lichens er movement to the one changed by the bobbin exchange Lace position

To reinforce and temporarily secure the thread spreading generated by the bobbin during the braiding process a compartment opener 100 (Fig. 26, 27) is assigned to the upper braid lifter 10. to secure the thread spreading until the needle 98 is pivoted into the open compartment formed from the braid threads.

Figures 21 and 22 show the design of the clapper. The figures provided with an exponent refer specifically to the second exemplary embodiment. The devices described in the figures without an exponent are used both in the 1st and in the 2nd embodiment. In the 2nd embodiment, the facilities that _t in Figures 6, 9, 10, 19 and 20 omitted.

ψ When braiding the legs of the net, the four bobbins 8 of a braided head are guided in the eight-shaped intersecting tracks. The control of the length of the net legs

follows through the control unit 14, which is rigidly connected to the normal unit 4. Lie number of braids in the net leg is determined by the number of punched cards. The number of lichen is in turn a measure of the length of the leg of the net.

In order to achieve a connection of the link legs, the clapper 8 are passed via the control switches 32 ¹ (Fig. 4 i 11 ¹ J 11 and 13) from one braiding head to the neighboring braiding head and thus interchanged

The exchange process is carried out by the control unit 14 (Fig. 23 to 25) triggered as soon as the predetermined length of the net is braided. This takes place from the control unit 14 via the switch 54 a current pulse that the pull magnet 56

the control switch 32 from the cam disk 64 to its starting position, moved back · During the following shift to the gear shown in Fig. 15, the cam 64 rotated by 180, but due to the curved path design does not produce any pivoting movement, in this one In this case, only the roller lever 65 lying next to it is moved. This results in an alternating movement that alternates the exchange of the clapper 8 between the Braided heads 1-2j 3-4; 5-6 etc. or the braided heads 2-3; 4-5; 6-7 etc. allows.

Due to the fact that they are the same in all braided heads Bobbin position both during the legal process and also during the bobbin exchange the braid lifter works 9; 10 (Fig. 16 and 17) now moved in a two-step cycle synchronously with the bobbin winding.
