Equipment for laying out the fabrics

 Nastilanie tissue is a preparatory process before cutting flooring to the details of the product. For laying out the fabrics to cutting the shop set the long tables depending on the maximum length obmalloc 8 - 12 m, width of 1.65 - 1.70 m wide fabrics and 1.1 - 1.2 m for narrow fabrics. The table height of 0.8 - 0.9 m. the Surface must be smooth but not very slippery; table cover with boards, ksilolita or parquet floors.

On the Leningrad sewing Association "salute" is used two-plane mechanical movable cutting table (Fig. 150); due to movement of the cap table of the possible thread cutting, which accelerates the turnover of scaffold table. Table length 13 m, the length of each mobile cover 1 and 2 is 6.5 m; the width of one cover of 1.6 m, the other (through) at 1.58 m For horizontal travel of caps table 3 serves as a winch drum with a diameter of 250 mm and a gear 4 with a gear ratio of 1:40. For lowering and lifting one cover section mounted on the control panel buttons "the Bottom" and "Top".

When nastilanie finished, rastersize by clicking the start button, sends a signal to the second zone; as a result, table cover, located in the first zone, down with the flooring of 300 mm and moves to the second area where the flooring is cut on the cutting machines. At the same time for the vacant area in the first place moves another cover for the subsequent laying out fabric etc.

The table is served by two nastily and one Carver that provides a certain rhythm that condenses the working day of kastelic and increases the capacity of scaffold table for 18 - 20% compared to conventional tables. 

At the Moscow production Association "Vympel" is used periplocoideae table, which is a mechanical device to move five caps - planes of the table. It takes the place of the two machine tables, each square horizontally arranged three planes (one is always free).

There is also semilocally flooring unit of the ANC-1 in Kiev OKB for laying out fabrics, which covers an area equal to the area of the three cutting tables. Two tables of three occupied by the unit, are used directly for the production process, and one Desk is for storage of finished decking. Nastilanie produced manually or by using a spreading machine. Method of laying out in the manual execution - serial, parallel, combined. Control units push-button, there are warning lights on the finished decks.

At the end of the cloth-spreading tables, set the device to mechanically lift a roll of cloth on brackets. Fixture is used for lifting a piece of fabric to the desired height when nastilanie by hand or for filling in fabric spreading machine and consists of a metal frame with a movable traverse.

To trim the fabric from the piece and to clamp the blade at the end of the table set special line. Such range is small, does not clutter passageways, provides a smooth line edge of the fabric and contributes to raising productivity (in two times in comparison with manual line with a knife of the type "plane").

To align the clamping of fabric at the second end of the flooring used mobile restrictive range. In multiple-deck for cutting fabric on the line of section used sectional line. The length of the table with both sides often mounted measuring ruler (roulette) parallel to one another. A cloth strip is laid in the early spreading of the table throughout its width prevents it from sliding the bottom of the canvas when nastilanie.

When nastilanie narrow backing and applied fabrics "in the book" using special ruler for fixation of a fold of the fabric. The line consists of two parts: one of them is attached to the table, the other removable. Nastilanie tissue performed manually or with the help of devices and mechanisms.

For laying out wool fabric she used mobile spreading machine (Fig. 151), which is a 1 truck moved by a motor along the rails on the cutting machine table. It has a conveyor belt 2, on which is placed a roll of tissue 3. The movement of the conveyor belt is synchronized with the movement of the carriage, allowing you to lay fabric on a table without tension.

The carriage can be rotated 180' around its axis, thus achieving the desired position of blades in the deck - "face down" or "face". For cutting tissue in any place of the flooring has a knife 4 is driven manually. Knife guides mounted on the carriage. 

Wadding machine of the type of the suspension of the carriage is applied at the Leningrad Association "salute" (Fig. 152).

The carriage 1 is mounted on the guide rails 2, suspended above the cutting table to the ceiling. Her dangling arrow-romanterrell 3, which can be rotated 180' when nastilanie tissues "face". The carriage is driven by an electric motor.

The use of devices for carrying tissue facilitates the work on laying of cloths in the flooring, however, are not yet fit to align the edges, mechanical scraps of fabric, a counter for counting the number of paintings.

Some garment factories to laying out the fabrics used flooring machine company Textima (Fig. 153). It is a 1 truck moved along the rail cutting machine table 2. To hold the ends of the flooring at the ends of the table has a clamping range of 3 and 4. Change of the direction of movement of the trolley is effected by limit switches. 

For laying out lining fabrics use truck (Fig. 154). The coil is held on the truck with the ball bearings fixed on the brackets.

The length of the deck is controlled by stops, which are mounted on the table from both sides. Stops are rubber shock absorbers. 

Work with truck flows in the following order. Roll the backing fabric is worn on the unwinding rod. The end of the fabric is carried out between the screeds truck and fix the pressure line on top of the table; then the worker moves the hand truck until it stops. Fold the fabric clamped on the table, and the truck headed in the opposite direction. The edge of fabric align the guide cones.

The use of truck when flooring facilitates working conditions nastily, helps to improve the quality of the flooring and increase productivity.

The Smolensk Association "Voskhod" project Central project and design Bureau of light industry (CPKMB) introduced mechanized Shuttle-targeted method of laying out three-and six-membered complex universal brigade (KUB). The method consists in complex mechanization of the entire process of cutting production and universal teams of workers of different specialties, all connected by a single rhythm in the work.

The equipment complex mechanization includes: 

GPT-61 - a truck roll (drive);

MRD-1 - monorail for supplying rolls of fabric; 

НЦ1Л-55A - two - and three-tiered storage; 

NSHP-61 - unwinding device to accept installation of the roll on the rolling pin, facilitate unwinding when nastilanie and the rolling roll to a storage device 

tshp-63 - self-propelled trolley for addressing rolls of fabric to the wadding tables; 

TSP-60 - truck for collecting cut; 

MRD-2 - a monorail for delivery cut; 

КШ0-0,25 - stacker crane in the storage area of the cut, where installed in fixed tiered rotary racks.

Shuttle-targeted method of laying out with the use of complex mechanization provides rhythm in all parts of the knife production is efficient and widely used in industry (Fig. 155). 

Currently TSNIISHP developed a new machine: textile inspection-cutting and spreading machine, currently undergoing testing and industrial testing.

Winding-cutting machine previously (before laying out) cut a piece of fabric paintings (segments) in accordance with the card. The machine is installed in the preparatory Department, thus, the fabric for flooring is supplied in the cutting Department the pieces, not rolls. 

Spreading machine is designed for laying out pre-cut and assembled of fabric. Nastilanie occurs with a mobile carriage, put the cloth without tension. 

This method accelerates and improves the process of laying out and turnover of tables, but increases the complexity of the preparation workshop.
