Abstract: An apparatus for manufacturing tablets for hot beverage brewing includes a reservoir feeding infusible loose food products, a grinding system for the loose food products to obtain grounds of a given size, a moistening system moistening the grounds to a given moisture content, a mixing and homogenizing system for mixing and homogenizing the grounds to a homogeneous mixture, a weighing system of the homogeneous mixture to obtain a dose of predetermined weight, a forming system forming the dose into a tablet of predetermined volume, an irradiation system for electromagnetic irradiation of the tablet to overheat the particles to a partial baking and/or sintering for compactness and self-supporting ability without an enclosure, and a control system acting on the grinding, moistening, homogenizing, system, forming, and irradiating systems to control particle size, moisture content, homogeneity, weight, volume and compactness parameters of the tablet and change water permeability of the tablet accordingly.

Abstract: A method of making a tablet for hot espresso beverage extraction includes the steps of grinding a brewable product to obtain a powder having a substantially uniform particle size, dosing a predetermined amount of the ground product powder, moistening the powdered product dose, homogenizing the moistened mixture to obtain a powdered product with a substantially uniform moisture content, forming the powdered product dose to obtain a disk-shaped or prismatic tablet, and supplying an amount of energy to the tablet to obtain a substantially compact and integral item. The step of supplying energy is carried out by irradiating the tablet with an electromagnetic wave beam to overheat and partially bake and/or sinter the particles of the powdered product and impart a relatively compact and self-supporting construction to the finished tablet. The electromagnetic wave irradiation step is carried out at the end of the forming step while continuously compressing the dose.

Abstract: The blocking device of a wheel rim on a tire-mounting machine is provided with a rotating support plate having a central hole, and includes a stem for engaging with the rotating support plate, and a cursor which is slidable on the stem and which includes a conical centring body and a device for activating for moving the cursor along the stem. The device for activating includes a mechanical transmission between a collar and a motor and the coupling between the cursor and the stem is such as to prevent rotation of the cursor about the stem.

Abstract: The blocking device (10) of a wheel rim (100) on a tyre-mounting machine is provided with a rotating support plate (5) having a central hole (6), and comprises a stem (11) for engaging with the rotating support plate (5), and a cursor (15) which is slidable on the stem (11) and which comprises a conical centring body (16) and means for activating for moving the cursor (15) along the stem (11). The means for activating comprise a mechanical transmission between a collar (20) and a motor (28) and the coupling between the cursor (15) and the stem (11) is such as to prevent rotation of the cursor (15) about the stem (11).
