    This work presents the analysis of the final shaping process of the patterns aimed at determining the influence of the pressure and the time of sintering on the resistance to bending. The analysis of the research results proved that when the pressure of the sintering rises and reaches Ps=2.1 bar the resistance to bending increases, above this level of the pressure the resistance value starts decreasing. The time of styrofoam sintering at which the highest bending resistance values were obtained is ts=90 s. When the sintering pressure is less than 2 bar prolongation of the time of sintering over 90 s causes a slight increase in the resistance, however, at higher pressures prolongation of the time of sintering causes submelting of the styrofoam pattern

    In this paper, the technology of forming patterns on a research station equipped with an autoclave A-600 of Polish company GROM is presented. This study was conducted to determine the influence of pressure and time of forming a pattern on the bending strength. Analysis of the results confirmed that bending strength increases with increasing the pressure. The time of forming a pattern has a similar effect

    The aging granulate is to activate the blowing agent during the manufacturing process to granulate models can re-expand and shape the model of well-sintered granules, smooth surface and a suitable mechanical strength. The article presents the results of studies which aim was to determine the optimum time for aging pre-foamed granules for pre-selected raw materials

    Zaprezentowano wyniki badań, które zostały przeprowadzone w listopadzie i grudniu 2014 roku. Respondentami badań ankietowych byli właściciele 20, spośród 24 aktywnie działających gospodarstw agroturystycznych na obszarze powiatu żnińskiego. Jak wynika z badań, dofinansowanie z UE oraz innych źródeł nie było głównym powodem podejmowania działalności agroturystycznej w powiecie żnińskim. Ważniejsza była chęć uzyskania dodatkowych dochodów z prowadzonej działalności. Badane obiekty charakteryzowała różnorodność ofert dla turystów, jednak ujemną cechą był brak typowo agroturystycznych atrakcji związanych z gospodarstwem rolnym. Stwierdzono także wysoki poziom zadowolenia właścicieli z prowadzonej działalności agroturystycznej. Wśród badanych osób, które były właścicielami gospodarstw agroturystycznych przeważali respondenci z wykształceniem średnim, w wieku 50 lat i więcej, prowadzący gospodarstwa do 10 ha oraz najczęściej były to kobiety.This study presents the results of surveys which were carried out in November and December 2014. The respondents were owners of 20, out of 24 farms operating in the area of Żnin District. Gaining additional profits from the agritourist activities was what they were interested in. The studied agritourist objects provided a big variety of offers. However, a lack of typical agritourist attractions, connected with farming, was found to be a drawback. It was found that the farm owners were highly satisfied with agritourist activities. The surveyed farm owners were mainly graduates of high schools, 50 years and more, running farms up to 10 ha and they were mostly women
