The essential part of this work includes the analysis of the stress distribution in the forming elements, the material flow in the pressing region, the briquettes density determination, and the energy-power parameters of the briquetting process. Considering the limited number of discrete elements that can be used for simulation, separate models were prepared to study specific parameters to achieve the best results.

[ Google Scholar] It’s really important to select the right temperature setting for the fabric you’re pressing. Materials made out of linen and cotton can take much higher temperatures than those made out of silk or nylon. Using too low a temperature can render your pressing ineffective, and using too high a temperature can permanently damage your fabric. Here are some recommended temperatures for popular fabric types:A complete model of material compaction in a roller press was developed, which makes it possible to determine the process’s power parameters and the material compaction’s characteristics, taking into account the characteristics of its constituent particles. The finite element method (FEM) is quite well developed and widespread in various fields of mechanics [ 31, 32]. This method has some ability to model in detail the compaction of fine-grained material in the rollers and, as a result, improves the optimisation of the technological process and equipment. It looks pretty attractive because it allows one to study the behaviour of fine-fraction materials and tribological conditions. However, there is a problem that this method is currently not sufficiently programmatically and theoretically developed for the study of multicomponent mixtures. That applies to fine-grained mixtures in which various components, fractions, and binders are present, including those containing a liquid phase. The results of calculations using the finite element method largely depend on the specific experimental data to determine, which requires quite expensive specialised equipment. There are studies on the application of this method to studying the parameters of briquetting, which investigated the effect of the configuration of the forming elements on the energy parameters of the process and the stress distribution in the compacted material [ 33, 34, 35, 36]; however, in the authors’ opinion, too much simplification was used in the presented works, e.g., rollers roll material spread out on a flat surface.

Uses: Foundation / English paper piecing, quilting, working with stiff cotton fabrics, pressing small areas. Seam presser / finger presser / seam creaser By pressing your seams you will set the stitches into the fabric, making your seams more durable and smooth, as well as making the seams blend and disappear into the fabric. This mechanism compensates for roll deflection caused by the load from the material. This ensures high-precision processing in the width direction, even when the load on the material or width of the material has been changed. Adoption of a function for setting roll temperature in accordance with the material’s properties One of the parameters that characterise the deformation region in a roller press is the amount of pressure exerted on the surfaces of the forming elements. Its value, considering the physical and mechanical properties of the compacted material, makes it possible to determine such parameters of the produced briquettes as density distribution and strength.
