Mat roll cutter
Šrámek, Michal ; Holub, Michal (referee) ; Foller, Bronislav (advisor)
The diploma thesis deals with the construction of a textile machine. More specifically, it deals with the construction of a vertical cutter of non-vowen fabrics that are made of polymerous fibres or fibre glass. The surface density of the material used ranges from 100 – 500 g/m2, the width of a role is 2000 mm and the weight is 150 kg. The machine is supposed to be designed in such a way so that the mat roles could be cut in any point.

Filament Winding Machine
Dorňák, Michal ; Hampl,, Štěpán (referee) ; Foller, Bronislav (advisor)
The aim of this diploma thesis is the proposal of solution of three-axial winding machine for winding technology of rotary profile. Winding materials are continual springs of carbon, aramid or glass fibre impregnated by resin. The main construction change of the machine compared to commercial available solutions is the use of linear motor as a frame element instead of roller screws or toothed chain. Linear motors have higher dynamics of the movement and they can reach higher speed compared to other solutions, which guarantee increase of the machine productivity. The main importance is put not only on the functionality but also on the low price of this solution. The 3D model of the mechanism is created in the program Inventor 2009.

Test Specimens Machine Tool
Dekař, Roman ; Plšek,, Ladislav (referee) ; Foller, Bronislav (advisor)
Diploma work deals with the proposal of single purpose maschine for the maschining of test dumb bells of polymer composite material filled with glass fibre. The purpose of this maschine is to process the test parts with dimensions of 3x5 mm up to 4x8 mm. The maschined part can have a profile with a maximum cross section 20 mm, or 20x20 mm. Based on the given parametres I prepared the proposal of the engineering process the overall set up including the drive force, its own feeding of the object, cooling and waste removal.

Glass Plates Manipulator
Zach, Jiří ; Kunta, Zdeněk (referee) ; Foller, Bronislav (advisor)
The object of this diploma work is to project a manipulator for the chaffs of glass, which will be mounted to the cutting machine RKP 01. The function of this manipulator will be a transposition of the chaffs of glass from the supply table to the haul. This manipulator check by calculations. RPK is the cutting machine for the circular-shaped cutouts, from which the saucers are made. Everything will be operated automatically, position of a handling moulding will be located by the sense organs and everything will be controlled by the automat, which was already designed by the firma FESTO FEC 30.

Polymerconcret Frame of Vertical Lathe
Buksa, Jan ; Marek, Jiří (referee) ; Foller, Bronislav (advisor)
This work describes construction and calculation of vertical lathe bed designed by request of company TOSHULIN. Apart from a sum of theoretical knowledge, the information contained in it should also serve in practice as a comprehensive guidance for construction vertical lathe bed from this material. The approach is specific by reason of that is necessary to observe functional proportions at contemporary producing part, which is usied for construction vertical lathes. There is a design of construction in this work, which gives better results mechanic, dynamic and thermal features of this part in some way.

Diaphragm Press
Krčál, Zdeněk ; Blecha, Radim (referee) ; Foller, Bronislav (advisor)
The aim of this thesis is constructional concept of diaphragm press for thermoplastic forming. The press consists of two chambers. First chamber is designed for forming of semi-finished product to forming temperature and second chamber is designed for heating the semi-finished product. Theoretical part of this thesis is focused on technologies in use and shaping of plastic description. Practical part of this thesis deals with detailed description of press concept including consistence calculations and drive units calculations. The whole concept, including its individual parts, is designed using the Autodesk Inventor software. At the end of this thesis, there is the economic and safety analysis.

Servodrive Clamping Unit
Štefánek, Tomáš ; Plšek,, Ladislav (referee) ; Foller, Bronislav (advisor)
The aim of this thesis is to design a clamping unit with mechanical multiplier. Unit will serve as a technological clamping element in the technical equipment. My task was to select the method of construction and design driving main unit for grip jaw. I chose a solution with a mechanical multiplier. The frame unit is made up of fixed and sliding clamping jaw and is self. Unit is designed as a built module. The entire structure must be designed to meet the initial parameters specified in the award of thesis. The main parameters include clamping strength of 80kN, the extent of working stroke 15 mm and the size of a scroll, which is 250 mm. They are also listed in the award size constraints: the length, width, height dimensions and the coupling unit.
