Definitions
- the present invention relates to an embossing apparatus, particularly for paper in roll form for products of the "tissue” type, such as for example kitchen paper, toilet paper, et cetera.
- Paper embossing machines for example for producing two-ply composite kitchen paper rolls, generally include an unreeling device which is suitable to feed with two plies of paper an embossing unit which may be provided with a system for pasting the two plies.
- the embossing unit can include two embossing cylinders, each of which has a series of protrusions arranged in parallel rows and cooperates with a respective presser cylinder to emboss each sheet.
- One of the two embossing cylinders can be coated with glue in order to paste the two sheets.
- the protrusions of the embossing cylinders are produced by chip-forming, or by chemical processes for removing material, so that the sheets have a uniform series of dimples constituted by parallel lines of points directed inward, that is to say, on the facing sides of the sheets.
- a knurling unit suitable to knurl the roll in order to join the two plies.
- An aim of the present invention is to provide an embossing machine which is suitable to provide even complex ornamental patterns on the finished product.
- a further object of the invention is to provide a machine which is far cheaper to run, from the production point of view, than known systems for producing complex designs.
- a further object is to provide a machine which is capable of producing ornamental patterns or designs which are more or less complicated according to the requirements and in a highly versatile manner, that is to say, with the possibility of varying the design quickly and cheaply.
- an embossing apparatus particularly for paper in roll form, comprising a device for feeding paper in roll form into a first embossing unit constituted by at least one embossing cylinder which is suitable to provide a first embossing on the paper, characterized in that it includes a second embossing unit, downstream of the first embossing unit, and suitable to provide a second embossing on the paper.
- an embossing apparatus generally designated by the reference numeral 1, includes a feeder 3 suitable to feed a first embossing unit 5.
- the feeder is constituted, in the illustrated example, by a reel unwinder which is suitable to feed the first embossing unit with two plies of paper 7 and 9.
- the first embossing unit includes a first embossing cylinder 11, with a corresponding rubber cylinder 13, and a second embossing cylinder 15, with a corresponding rubber cylinder 17.
- there is a pasting device 19 which is suitable to spread glue on the cylinder 15 in order to paste the two plies 7 and 9.
- the cylinder 31 is made of steel and engraved and is suitable to work by contrast with the cylinder 23, which is made of smooth steel.
- the embossing cylinder 31 is made of very hard rubber and works by contrast with the cylinder 23, which is made of smooth steel.
- the embossing cylinder 31 is made of steel and has a nickel or fiber-reinforced plastic jacket which is suitable to support a cliche made of very hard rubber, on which the design is formed by photoengraving, laser or other known methods.
- the cylinder 31 works by contrast with the cylinder 23 made of steel or optionally made of a softer rubber than the cylinder 31.
- This system has some important advantages: it is in fact possible to change the design on the paper in a very short time, because the jackets can be extracted in a cantilevered manner, without disassembling the cylinders.
- photoengraving or laser methods it is also possible to provide designs with high definition much more simply and cheaply than the provision of designs by conventional machining.
- the ribbon 21 is thus subjected to a second embossing, which is superimposed on the first embossing provided by the first embossing unit.
- the head of the re-reeling machine may include a knurling device 29, which is optionally provided if, for example, the two plies are not pasted.
- the machine according to the invention allows to provide complex designs and ornamental patterns. While the first embossing unit can provide a conventional geometrical pattern, the second embossing unit can in fact be used to superimpose a particular design.
- the invention achieves the intended aim and objects; it is in fact extremely simple to provide complex ornamental patterns by overlapping two separate embossings.
- the machine according to the invention is extremely flexible; it is in fact possible to vary the design on the paper simply by replacing the second embossing cylinder; moreover, the second embossing unit can be easily bypassed if one wishes to emboss the paper in a conventional manner, with a simple design, due to production requirements.
