Furthermore, the Hechen program (basic software for a box of a certain type) all other dimensions and contain conversions that are important for the construction of such a box. (For example the Radius of the arc drawn in on Fig. 1 and the angle alpha required for proper closing).

Figure 2 shows a folding box of the same type (BoχA), but with the dimensions 40 by 40 by 100, the cardboard thickness 0.5 and the bridge width 5 are now shown,

Figure 3 shows a box with a modified tuck-in flap, rounded, calculated according to the BoxB program. Dimensions 20 x 20 x 55 cardboard thickness 0.5 mm, bridge width 5 mm.

It should also be noted that all the folding box blanks shown are true-to-size copies of Represent shapes that are calculated by a computer and then numerically without further intermediate work controlled laser machine.

Claims (1)

The method, characterized in that for the manufacturing process of a steel strip cut with a NC-controlled laser saw a computer system is used to create the control hole stripe, runs as in Described below. 1.) The desired program is transferred from the external memory of the computer system to the core memory read in. E.g. the folding box blank BoxA according to the enclosed figure 1. 2.) After reading in, the computer starts the input procedure {that is, asks about the dimensions of the Folding box. The expression then looks like this: Folding box type BOXA width? The third measure? Length? Cardboard thickness? Bridge length? The operator answers the questions by typing the dimensions z. B. in mm immediately after the question mark. In the case of Figure 1, which incidentally shows the folding box size calculated by a computer, so you get the following input dialog ζ Program folding box type BOXA width? 30 The third dimension? 30 Length? 60 Cardboard Thickness? 1.0 Bridge length? 5 3.) After the initial dialog, the operator gives the start signal for the calculation and the computer calculates all necessary route instructions for the NC control and punches the individual commands the control tape. 409884/0511 -fc. km ) If the control program were to be punched by hand using a telex typewriter, the following commands would be required for the first part of the box from Fig. 1: Set no.

that for lengths from 50 mm two bridges, for lengths from
12Q now three bridges remain in place. - 5 409884/051 1 6.) The method is also characterized in that after creating the control strip or at the same time by the computer, a second perforated tape (or another data carrier) is created on which the dimensions for the subsequently sawn out or better ^{M in a suitable code} The steel lines (cutting or creasing lines) to be lasered out are recorded. This data carrier is inserted into the automatically operating cutting machine, which both cuts the lengths and punches out the bridges. 7.) Method characterized in that both the laser sawing machine and the cutting machine directly are connected to the computer (so-called on-line operation) so that the use of a data memory (external data storage) such as perforated tape, punched cards, magnetic tape, magnetic disk or drum is not required for the To output information to the respective processing device.
