Embodiment Construction

[0014] Reverting to its basic structure and referring to the illustrations in the drawings, the switchable embossing device of the present invention includes a structure 1 having two fixed sides 10, with two movable sides 11 hinged to the two fixed sides 10 on. Each of the fixed side portions 10 has an outer surface EF and an inner surface IF, and the inner surface IF faces the corresponding movable side portion 11. Similarly, each movable side portion 11 has an outer surface EM and an inner surface IM, and the inner surface (1M) faces the related fixed side portion 10. The inner surface IF of each fixed side portion 10 has two circular arc-shaped notches 12, 12', one notch 12 is set slightly higher, and the other notch 12' is set slightly lower. The inner surface IM of each movable side portion 11 has two similar notches 13, 13', and these notches are also arc-shaped. To be better described in detail below, the notches 12, 12', 13, 13' provided in the inner surfaces IF, IM of the...

Abstract

Convertible embossing device comprising a structure (1) with two fixed sides (10) and two mobile sides (11) with respective external faces (EF, EM) and internal faces (IF, IM) and provided with, in correspondence of the respective internal faces (IF, IM), two upper recesses (12, 13) and two lower recesses (12', 13') with a circle-arc profile intended to support the end flanges (20, 30) of the two embossing rolls (2, 3) orthogonal to the sides (10, 11) of the same structure (1), wherein the mobile sides (11) are joined to the fixed sides (10) and the respective upper and lower recesses (12, 13, 12', 13') define, by cooperating with one another, two pairs of circular seats for the flanges (20, 30) of the rolls (2, 3), and in that, in a second operating position, the mobile sides (11) are distanced from the fixed sides (10) and the upper recesses (12, 13) of the sides (10) and (11) define, each one by cooperating with corresponding semi-circular closure flanges (15, 16), two pairs of circular seats for the flanges (20, 30) of the rolls (2, 3).

Description

Technical field [0001] The invention relates to a switchable embossing device. Background technique [0002] As we all know, embossing is a mechanical process that transfers multiple patterns to easily deformable materials, such as roll paper or "laminated" paper. To this end, the material to be embossed passes through an embossing machine, which includes a pair of counter-rotating steel rollers and a pair of corresponding pressure rollers, the steel rollers basically having point-like protrusions. In so-called "nested" embossing, the protrusions on the rollers of the calender correspond to the recesses defined by protrusions on other rollers during manufacturing. In the case of so-called "tip-to-tip" type embossing, the protrusions on the rollers always correspond to the protrusions on the other rollers during manufacturing. In order to change from one type of embossing to another type of embossing, it is necessary to stop the manufacturing work every time, and rebuild the devic...
