Abstract

The invention relates to equipment for blank production and can be used for cutting sheet and briquetted light-Fusible material, including packaged or reinforced with a polymer film. The aim of the invention is to increase productivity. Each heated string 2 is provided with a scoring non-heated string 4, which is spaced apart from the cutting heated string by an adjustable distance. The undercuts of the non-heated string are made of a smaller diameter than the heated cutting string, and to ensure an optimal distance between the cutting heated and the additional strings, the spreading rollers 5 with shaped grooves are installed. The number of parallel-installed string pairs is determined by the size of the briquette and the required dimensions of the preform. The process is easily automated, 2 3.p. f-ly, 3 ill.

The optimum distance between each heated cutting and cutting unheated by the strings is established by selecting spacer rollers with shaped grooves of insulating heat-resistant material located at the ends between the strings (Figs. 1 and 3).

sheet or briquetted low-melting material, including un-rolled or reinforced with a polymer film.

The purpose of the invention is to increase productivity.

Fig, 1 shows the proposed device, a general view; figure 2 - section aa in Fig, 1; Fig, 3 - spacer roller.

The device contains a table 1 with slots for a cutting tool made in the form of tensioned heating M1.IX strings 2j fixed at one end stationary and at the other with the help of an elastic element 3 providing constant tension of strings and undercutting unheated strings 4, remote from the cutting strings 2 on the

The device works as follows.

When the table 1 moves upwards, the heated strings 2 melt the briquette material in the cutting plane. In this case, the poly-35 cutting plane from the cutting heat-measuring film is cut, and the main material of the briquette turns into a plastic state and with further movement is cut by additional strings 4 already without gluing

In order to ensure optimal undercut conditions and, as a result, increase the speed of undercutting with an unheated string, the latter are made of a smaller diameter than the heated cutting strings.

The cut material is removed from the table by an ejector (not shown), after which table 1 returns to its original state, a new briquette 8 is loaded, and the nick

repeats.

The optimal distance between each cutting heated and undercut unheated by the strings is established by selecting the spacer rollers with shaped grooves of insulating heat-resistant material located at the ends between the strings (Figs. 1 and 3).

The number of parallel-installed string pairs is determined by the size of the briquette and the required dimensions of the preform. The whole process is easily automated.
