Description
- The present invention relates to a lateral protective element of a flexographic sleeve of a machine per flexographic printing.
- It is known, that flexography is a direct rotary relief printing method and is alike to typography inasmuch as it uses resilient printing plates made of rubber or photopolymeric materials.
- The printing plate is fixed on a sleeve which in turn is keyed on a rotating mandrel and is inked by means of a batching roller known as an "anilox" which is cell-structured, with the cells transferring the quick-drying printable liquid ink onto virtually any support, either absorbent or non-absorbent.
- It is also known, that such a sleeve is formed by a multilayer cylinder having a cylindrical axial cavity for insertion on the mandrel and two protective elements applied on the base of the cylinder.
- One of the two protective elements is provided with a register slot engageable by an abutment provided on the mandrel for guaranteeing the correct angular position of the cylinder on the mandrel.
- At present the register slot is realised on an L-shaped aluminium block which is fixed by a screw to a flat ring made of a different material acting as a protective element.
- The internal edge of the base of the cylinder has a notch having a shape complementary to a wing of the L-shaped block in which the block is housed when the flat ring is glued to the base of the cylinder.
- This assembly procedure of the sleeve is rather elaborate and complex and the lengthening of the assembly times inevitably leads to an increase in production costs.
-

- In the scope of this task, the object of the invention is to realise a construction for a sleeve per flexographic printing which enables a simplification of the assembly procedure and, in the end, saving production costs.
- This task, as well as these and other aims, are attained by a lateral protective element that is applicable to a sleeve for flexographic printing according to
claim 1. - Further preferred embodiments of the present invention are defined in the appended dependent claims.
