FIELD: process engineering.
SUBSTANCE: invention relates to packages. Proposed set comprises first, second and third stamping rollers R1, R2, R3. Note here that first roller R1 stays in contact with second and third rollers R2, R3 while foil 9 can be forced between first and second and between first and third rollers for hot-pressing and stamping. Note that first roller R1 has teeth making the main grid GR, GR1 and separate teeth 5, 35. Other two rollers R2, R3 have surface structure other than that of said first stamping roller. Note that one of said two rollers R2, R3 has surface structure (A, B, B, G, H, J; Q, R, S, X, Y, Z) with structural elements (11, 13, 15, 16; 17, 18, 19, 21) arranged separately or as sets but not as the main grid GR, GR1 of said first stamping roller. Note here that every structural element (11, 13, 15, 16; 17, 18, 19, 21) consists of separate teeth 5, 35 or of continuous ridges 19, 21, or of combination thereof. Note that said teeth and/or ridges are spaced apart. Note that structural elements are arranged in circle, extend in lengthwise direction, or in spiral on second and/or third stamping roller R2, R3.
EFFECT: perfected design.
