A disadvantage of the known device is Td, that it does not allow for the on-line drawing of sewing patterns at. moving to a new size or growth.

The aim of the invention is to expand the functionality of the device.

The goal is achieved by the fact that the proposed device contains a decoder and an OR element, and the control unit consists of a serially connected control panel and a control unit, while the interpolator control output is connected to the memory unit and, through the serially connected OR element and trigger, to the reading unit information, the register output is connected to the decoder and through the I element to the computing unit, the first output of the decoder is connected to the second trigger input, the second output via the control node to the second course and the third OR output - to the second input element I.

The memory block contains input, main, intermediate and auxiliary registers and additional elements AND, the input registers are connected to intermediate and auxiliary registers, the outputs of which through the additional elements AND and the main registers are connected to the corresponding inputs of the interpolator, and the inputs of the input registers are connected to the corresponding the outputs of the control panel, the output of the computing unit is connected to the inputs of the auxiliary and intermediate registers, and the output of the interpolator is connected to the second inputs additional elements I.

The drawing shows the block diagram of the device.

The device contains an information reading unit 1, through a register 2 and an element AND 3-associated with a computing unit 4. A decoder b and an output element OR 7 are connected to the inputs of the trigger 5 and a control unit 8 is connected to one of the inputs of the element OR 7, which consists of serially connected control unit 9 and control unit 10. To the second input of the element OR 7, an interpolator 11 is connected, connected by its second output to information recording unit 12. Memory unit 13 includes input registers 14 (Ry and RVI), which are intended for storage sizes of sizes and growths of patterns, intermediate registers 16 (from R to RX), which. they are intended for storing intermediate results of calculating the coordinates of the patterns of the size of the cut produced. The memory unit 13 also includes the main registers 16 (and RY) for storing the displacement values along the coordinates and connected via additional elements and 17 to the auxiliary registers 18. The outputs of the control panel 10 are connected via the input registers 14 to the intermediate 15 and auxiliary 18 registers . The outputs of the main registers 16 are connected to the corresponding inputs of the interpolator 11, the output of which is connected to the second inputs of additional elements 17. The second output of the decoder 6 is connected to the control unit 9, and the third output is connected to the second input of the element 3, trigger output 5 is connected to the unit 1, and register 2 is connected to the input of the decoder 6. The device operates as follows. A punched tape with the coordinates of the points of the base piece on it and inter-dimensional increments at specific points is entered into the information reading block 1, which, under the influence of the trigger 5, produces frame-by-line input of information from the punched tape. Calculation of coordinates is performed sequentially for each point of the contours of the piece using the formulas + + p, + S, n + r, m where, the coordinates of the singular point on the piece size, and -th height; X, y - coordinates of the singular point on the base piece; m, n are, respectively, the number of sizes and growths between the derivative and the base piece, where the distance from the average for the account is 40 times the same, and those are the same as Y and along the r, point relative to the previous singular point by one size,), Sy is the same, by one height. .4 |.

Retat multiplication enters pp 15 (Rb-X), intended to accumulate the value of X. m (vein m is set on register 15 for size R). The contents of Rb-X are cleverly added to the result, the result remains in block 13. The punched tape is read by X and added in block 13 with the previous amount, as a result, the X value is transferred to page 18 (Rb X). Taxable quantities are handled., PG, Y, and semi The value is stored in register 18 (Rb-Y). Further, using the formulas 3, 4, the quotients K and K j are calculated in the following manner: - the result of the multiplication is stored in the register RY 15. -XY - the result remains in block 13. the result remains in block 13. -X -X - result in the register. - Y-.

The interpolation end interpolation signal of the previous segment of interpolator 11 sets the trigger 5 to one state, and at the same time enables the rewriting of information from the auxiliary registers 18 to the main 16. At the same time, the interpolator 11 and the computing unit 4 simultaneously receive a new piece of information that is processed in parallel in them . This improves the performance of the device. From the output, the readout block 1 of the eight-bit data enters through the input register 2 to the decoder 6. The decrypted address information allows the AND 3 information to pass through the corresponding digital information from the register 2 to the computing unit 4, where the coordinates for the new dimension of the dimension are calculated. The result of the calculation is derived from the temporary storage register of the coordinates Rb-X and. When the end of frame sign arrives at the decoder 6, the decoder issues a prohibition signal for the trigger 5 and reading from the punched tape is stopped. The task of the necessary size and growth is made from the control panel 10 and transferred to the registers 14 R and
