Design of cutting unit
Jelínek, Pavel ; Košťál, David (referee) ; Brandejs, Jan (advisor)
This thesis deals with a structural design of a cutting roller including a proposal for its drive and exhaust system of the flexography machine Premia produced by Soma spol. s r.o. company. The first part discusses the technology of flexography and about the issue of cropping and extraction of material in general. Another part discusses the optimization of these systems, including the final engineering design. The main outcome of this thesis are drawings of assemblies listed in the annexes.

Reversing cross for flexo printing machine
Falta, Jan ; Mazal, Pavel (referee) ; Brandejs, Jan (advisor)
The aim of this work is to develop a new concept of the reversing cross for flexo printing machine SomaFlex Optima. Work includes a description of the machine, the basic description of the principle of flexography. There is explained the principle of turning the material, the current method of supplying air to the air cushion and the difference between the blower and compressor as an air source for the air cushion. Conceptual solution includes two variants, namely vertical and horizontal position of turning bars. For each alternative are described its advantages and disadvantages.

Design of cooling roller mounting and driving
Skalický, Lukáš ; Omasta, Milan (referee) ; Brandejs, Jan (advisor)
The basic aim of this bachelor’s thesis is design of double-surface cooling roller driving for flexographic printing machine Mini 80-EG, which is manufactured by company SOMA spol. s r.o. Next aim is design of this roller, its mounting and cooling water inlet into inner space. Design is based on more calculations. The most important of them are listed in bachelor’s thesis. Bachelor’s thesis includes profile of submitter and principle of flexography’s brief description too. Results are identified at SOMA’s disposal. The main output is complete design documentation. The most important drawings are located in supplements.

Design of cleaning unit of central impression cylinder for flexographic printing machine
Falta, Jan ; Maňas, Pavel (referee) ; Černohous, Pavel (advisor)
This master´s thesis is focused on design and manufacturing of prototype of central impression cylinder cleaning unit. This thesis contains explaining of basic principle of flexographic printing and preview of types of flexographic printing presses. There are explained patented cleaning units and main claims of every patented cleaning unit. In the next part of this thesis, there are some conceptual designs, from which was chosen the final design for manufacturing. In the next part of this work, there are detailly described each of the parts of cleaning unit. Prototype of the cleaning unit was manufactured and tested in the SOMA Engineering s.r.o. Lanškroun. Cleaning unit will simplify the work of operators and reduce time, needed to clean the central impression drum in comparison with manually cleaning.
