Description

GERMAN

The invention relates to a method for producing tubular fabrics on flat looms. in particular a laundry carrier belt with a homogeneous insert. Foam rubber, plastic foam or similar resilient material, which between laterally offset .Weblitzeji these continuously is fed and then a weaving reed in a corresponding to the cross-section of the insert, serving as a guide and. not the full breadth of the Webrietes. engaging opening, penetrates.

Laundry carrier belts of the type mentioned are up to now in larger lengths by .making, e.g. by sewing .two ribbons with intermediate insert or by inserting the the latter in a double-laid tape and then sewing the edges on top of one another made of the tape. Shorter sections are made in that one piece of a hose band a corresponding length of the insert is drawn in by hand. The invention is based on the Finding out that the production of laundry carrier tapes with deposits of the type mentioned is simplified and can be cheaper if the insert is included in the tubular fabric during its manufacture is woven in. The object on which the invention is based is therefore to develop a method for weaving. a homogeneous insert made of foam rubber, plastic foam or the like. In a Tubular fabric, in particular in a laundry carrier belt, and in the creation of one for implementation ribbon loom suitable for the process,

There is already a method of making hollowware using a double and Known of three web shooters, in which alternating an upper and a lower shot and at the same time with each of these two shots a center shot is entered. However, this method is for manufacturing of tubular fabrics with a flexible insert of the aforementioned type cannot be used. But there are a method and a device for the production of filled textile tubes are also known, especially for the production of asbestos-filled insulating strips. Here is a flat loom used with a movable reed having an opening corresponding to the cross-section of the insert and does not occupy the entire width of the Webrietes. The inlay becomes the opening continuously fed between laterally offset strands, for which a special control device is provided. Mediating With a corresponding connection, the movable reed is forced to become dependent on time to raise and lower from the strand movement. The asbestos insert is inserted via a funnel-shaped insert Metal tube that goes into the reed opening

In contrast, there is the invention in a method of the type mentioned in that using a fixed Webrites and one in a manner known per se in the manufacture of warp pile fabrics the warp threads formed the double shed the upper shed above the opening and the lower compartment under the opening and at the same time on both sides of the opening through those not involved in the formation of the double compartment A large shed is formed for each warp thread in order to pass through the loom with every turn of the loom two weft threads inserted into the compartments at the same time, the upper and the lower side of the tubular fabric and the connection of the top with the bottom to the. both edges, des Fabric.

Claims (2)

Nende ribbon loom has the combination of the following features, some of which are already known per se: a) that a fixed weaving reed is provided, b) that the weaving reed has a central opening which corresponds to the cross section of the flat insert and serves as a guide, c) that a Double shed device is provided in order to allow the two shuttle shuttles guided over and under the insert to simultaneously pass through the respectively formed upper and lower shed with each loom rotation. Various advantages are achieved simply by using a fixed weaving reed. The immobility of the reed eliminates all difficulties that the use of an indirectly or indirectly raised and lowered reed would entail when weaving in the flexible insert. The flexible inlay does not need to be guided through a strand and is not subject to abrasion or strength. It can thus consist of a material which, because of its low abrasion and tear resistance, could only be woven into a loom with a movable reed under special measures and using additional devices, such as those provided for example in the known loom described. The fixed weaving reed is provided in a ribbon loom, which enables the production of a ribbon-shaped tubular fabric with a flexible insert, in particular a laundry carrier belt with a wide flat insert made of foam rubber, plastic foam or the like, in a cost-saving weaving technique. In a manner known per se, the weaving reed has a central and not taking up the entire width of the reed. serving as a guide opening through which the insert passes. By adapting this guide in the fixed weaving reed, the introduction of the flat and relatively wide insert strip is made possible. In the case of the ribbon loom according to the invention, a double shed device is furthermore provided in order to allow the two shuttle shuttles guided over and under the insert to simultaneously pass through the respectively formed upper and lower shed with each loom revolution. This measure is known per se in a loom for the production of warp pile fabrics; However, it has not yet been proposed for ribbon looms and certainly not for a ribbon loom with a central guide in the reed, let alone for a ribbon loom in which the central guide is provided in a fixed reed . The combination of all of the features described results in a ribbon loom which advantageously enables the object on which the invention is based to be achieved. . The drawing explains the method according to the invention and the ribbon loom developed for its implementation using an exemplary embodiment. It shows Fig. 1 a schematic representation of a course in a ribbon loom in a vertical section through the tubular fabric, Fig. 2 is a plan view of the course and Fig. 3 the associated weaving reed. The illustrated embodiment relates to the production. a laundry carrier tape with a foam rubber insert -of a flat rectangular cross-section. The interlining 4 is fed to the weaving point in the direction of the warp threads 5 to 8 (Fig. 1), the strands 9 being laterally offset to allow the interlining 4 to pass through (Fig. 2). The opening angle between the central warp threads becomes smaller, the greater the distance between the heald frames 9 and the fixed weaving reed 10. In Fig. 1 and 2, this distance is shown reduced compared to the dimensions of the belt 11 to clarify the arrangement. The insert 4 penetrates the fixed weaving reed 10 in a guide 12 (FIG. 3) which is adapted to the cross section of the insert 4. The warp threads 5, 6 form an upper shed and the warp threads 11 8 a lower shed in that they run between the reed sticks interrupted by the guide 12 and are controlled accordingly by the heald frames 9. The warp threads 5, 6 and 7, 8, in cooperation with the weft threads 14 'and 13' entered simultaneously by the two shuttle 14 and 13, form the two flat sides 11 a and b of the tubular band. The chain threads 5 ', 6', T, 8 'running between the uninterrupted reed rods on the side of the guide each form a large compartment and bind with both weft threads, whereby the edges 15 of the two flat sides Hfl and 11 δ of the tape are connected to one another will. The guide 12 in the fixed weaving reed 10 and the double shedding with simultaneous entry of the two weft threads make it possible in a simple manner to continuously weave an endless, flexible insert of any cross section into a tubular fabric.

Production of tubular fabrics on flat looms, in particular a laundry carrier tape with a homogeneous insert made of foam rubber, plastic foam or similar flexible material, which is continuously fed between laterally offset healds and then a weaving reed in a guide that corresponds to the cross-section of the insert and serves as a guide and not the penetrates the entire width of the weaving reed occupying opening, characterized in that using a fixed weaving reed (10) and a double shed formed by the warp threads (5, 6, 7, 8) in a manner known per se in the production of warp pile fabrics the opening (12) and the lower shed under the opening (12) and at the same time on both sides of the opening (12) through the chain threads (5 ', 6', 7 ', 8') not involved in the formation of the double shed large compartment - is inserted into the compartments at every turn of the loom through the two at the same time carried weft threads (13 'and 14') at the same time to establish the upper and the lower side of the tubular fabric (11) and the connection of the upper side (11 a) with the lower side (11 b) at the two edges (15) of the fabric . ■ 2.
