“…With the growing importance of sustainability and recycling, the current research effort leads to the development of numerous new constructions and technological solutions [1][2][3][4][5][6][7][8][9] or modernization of existing solutions; the intention is to limit the usage of natural resources. This trend for sustainability is observed in practically all the industry branches, even the down and feather industry recycles used down jackets in order to reuse the material.…”

The need to diversify the sources of raw materials used in industry has resulted in the increasing popularity of recycled materials. This situation is also observed in the clothing industry, which shows a growing interest in using recycled down and feathers from old jackets. Because the recovery process was being carried out manually, it is necessary to automate the process. Designing a suitable device requires testing to allow the modeling of the process to be carried out by the machine. The article presents the results of experimental tests whose purpose was to determine the material properties necessary to carry out numerical simulations of the destruction process of polyester fabrics. The article further presents the research methodology together with the research stand and discusses the results obtained.

Drive and conveyor belts are widely used in processing and mining industries. One of their types, which are often used in light-duty applications, are the belts with round cross-section and several millimeters in diameter. They are often made of thermoplastic elastomers, in particular ofweldable polyurethane. Their production process requires to carry out the operation of joining the belt ends to obtain a closed loop. This operation is often carried out by means of butt welding utilizing the hot plate method. This process is often performed by hand using simple tools. Authors took an effort to design the automatic welding machine, which can make durable joints of this type automatically. The design works comprise control system configuration which calls for identifying the technological parameters of the process, being the reason for undertaking the research works on the hot plate welding process. The main aim of this activity was to formulate of the mathematical model of the hot plate welding of round drive belts which is necessary to identify the process parameters and the correlations between them. In the paper, the assumptions for the hot plate welding process modeling were presented. During their formulating, technical conditions were taken into consideration resulting from some of the characteristics observed in an automatic welding device prototype which had been implemented for industry production.

“…The purpose of the experiments carried out as part of the PhD thesis research work was to determine the parameters relevant to adhesive bonding of polyurethane, reinforced synchronous belting and PU or polyamide fabric facing and the influence of these parameters on the bond strength, in particular determined by rolling of the belt around a circle. There is a noticeable interest in issues related to increasing process efficiency in the literature [18][19][20][21]25,26]. Research is being carried out, among other, to improve processes related to belt perforation [1,22], as well as to modification of machines carrying out the process of gluing plastics [13,23,24] and power transmission through belts [19].…”

Belt conveyors, equipped with belts designed for transporting materials and finished products are used in many industries. They allow to transport delicate items, for example made of glass, heavy products, such as canned food products and lightweight items, such as cardboard boxes. For this reason, the conveyor belts must, besides transferring power, ensure adequate conditions of transport for the conveyed materials without compromising the service life of the belt. Homogenous belts may not be capable of meeting all these requirements at a time. Composite belts, composed of the load-bearing layers and covering materials adhered thereon with the purpose to modify the surface properties, can be an option of choice in such cases. The described experiments were carried out on the respective materials making up composite belt joints as part of the research efforts related to the PhD thesis on adhesive bonding of composite belting materials. The strength tests were carried out on dumbbell-shaped specimens that were prepared from the load-carrying layer of synchronous polyurethane belting, the facing materials, namely polyamide fabric and polyurethane foam and the polyurethane adhesive used to join these layers. The differences in the parameters describing the surface properties, i.e. hardness and roughness were also checked. The experimental results were used to determine the material and strength properties of the components and the resulting differences were analysed.
