  • the device 1 also comprises:
  • the cutting body 13 can be releasably coupled to the base body 8 so that the peripheral portion 15 accommodates, at least partially, the raised portion 11 and so that the cutting tooth 16 engages the groove 17 to determine a cut of the sheet 4 and the production of a membrane 2 for separating a piece of the sheet 4 by said cut.
  • the peripheral portion 15 has an axial extension from the main portion 14 that is less than the axial extension of the raised portion 11 from the supporting base 10, so that the raised portion 11 is partially, and not totally, accommodated within the peripheral portion 15 during said coupling.
  • the cutting tooth 16 is annular, in particular circular, about the axis C and the groove 17 is annular, in particular circular, about the axis B.
  • the cutting tooth 16 and the groove 17 could have a profile defined by any closed-line endless profile around the respective axis C, B, for example a profile that is square with rounded corners, square, rectangular, polygonal, etc.
  • the resulting membrane 2 will have a perimeter tracing the profile of the cutting tooth 16 and the groove 17.
  • the cutting tooth 16 and the groove 17 have the same profile, so that one engages the other as a result of the coupling between the cutting body 13 and the base body 8.
  • the cutting tooth 16 and the groove 17 are conveniently arranged at the same radial distance from the respective axes C and B, so that the cutting tooth 16 engages the groove 17 during the above-mentioned coupling.
  • the raised portion 11 comprises a frustoconical portion 18 extending from the supporting base 10 coaxially to the axis B and the peripheral portion 15 comprises a frustoconical portion 19 extending from the main portion coaxially to the axis C.
  • the one frustoconical portion 18 and the other frustoconical portion 19 are configured to slidably cooperate with each other during the coupling of the cutting body 13 with the base body 8 to determine the centring of the axis B with the axis C.
  • the frustoconical portion 18 comprises an external frustoconical lateral surface 18a and the frustoconical portion 19 comprises an inner frustoconical lateral surface 19a configured to slidably cooperate with the surface 18a during the above-mentioned coupling, so as to determine the centring of the axis B with the axis C.
  • the one surface 18a and the other surface 19a face each other when the cutting tooth 16 engages the groove 17.
  • the one surface 18a and the other surface 19a are parallel to each other when the cutting tooth 16 engages the groove 17.
  • the user is able to perform the above-mentioned centring easily and without having to worry about precisely coupling the base body 8 and the cutting body 13, and without the aid of axial guiding elements for the cutting body 13.
  • This centring will cause, in use, the correct alignment between cutting body 13 and base body 8 and, thus, between cutting tooth 16 and groove 18, thus determining a cut in the sheet 4 under rating conditions.
  • the frustoconical portion 18 is tapered toward the axial surface 12 and the frustoconical portion 19 is tapered toward the main portion 14.
  • the device 1 is configured to be used with the base body 8 arranged on a support surface (not shown) so that the axis B is perpendicular to the support surface (vertical, if the support surface is horizontal) and the axis C is perpendicular to the support surface (vertical, if the support surface is horizontal) after centring and coupling has been completed.
  • the support surface may be defined by a user's hand.
  • the support plane is horizontal, it can be said that the one frustoconical portion 18 and the other frustoconical portion 19 are tapered upwards.
  • the above-described configuration not only allows centring of the axis B with the axis C, but also causes a tensioning of the sheet 4 radially outwards, prior to the cutting of the sheet 4 itself.
  • the one frustoconical portion 19 slides from top to bottom along the other frustoconical portion 18. This movement, in addition to determining the centring of the axes B and C, causes a substantially, axially symmetric tensioning of the sheet 4 in an outward radial direction.
  • the sheet 4 is well stretched and the cutting tooth 16 can easily penetrate it, compared to cases where the sheet 4 is not well stretched, and can therefore easily cut it cleanly and neatly.
  • the frustoconical portion 18 is preferably tilted in relation to a direction orthogonal to the axis B by an angle ⁇ between 40° and 70°, preferably between 50° and 60°, even more preferably 55° ( Figure 3b ).
  • the frustoconical portion 19 is inclined with respect to a direction orthogonal to the axis C by an angle ⁇ between 110° and 140°, preferably between 120° and 130°, even more preferably 125° ( Figure 3b ).
  • the cutting tooth 16 and the groove 17 conveniently have the same axial extension.
  • the cutting tooth 16 fully engages the groove 17 during coupling of the cutting body 13 with the base body 8.
  • the device 1 is thus compact and sliding cooperation between the frustoconical portions 18, 19 is ensured.
  • the cutting tooth 16 comprises an axial cutting wall 16a, which is substantially flat and perpendicular to the axis C. More specifically, the cutting tooth 16 has, in axial cross-section, a substantially quadrangular, in particular rectangular, profile, wherein the cutting wall 16a defines the axial end surface of the axial prominence defining the cutting tooth 16.
  • the cutting tooth 16 is defined by a substantially cylindrical, hollow axial protuberance and is, moreover, free of a sharp axial cutting surface, i.e., a cutting edge or blade.
  • the groove 17 comprises an axial abutment wall 17a that is substantially flat and perpendicular to the axis B. More precisely, the groove 17 has, in axial cross-section, a substantially quadrangular, in particular rectangular, profile, wherein the abutment wall 17a defines the bottom axial surface of the axial recess defining the groove 17.
  • the cutting wall 16a is configured to abut against the abutment wall 17a when the cutting tooth 16 engages the groove 17, so as to determine the complete separation of the membrane 2 from the sheet 4.
  • the separation occurs, in particular, at the inner diameter of the cutting tooth 16 and of the groove 17.
  • the raised portion 11 further comprises a cylindrical portion 20 coaxial to the axis B and extending axially from the frustoconical portion 18 to the axial surface 12; and the peripheral portion 15 also comprises a cylindrical portion 21 coaxial to the axis C and axially interposed between the main portion 14 and the frustoconical portion 19.
  • the raised portion 11 consists of the frustoconical portion 18 and the cylindrical portion 20 that overlies the frustoconical portion 18 and has the axial surface 12; and the peripheral portion 15 consists of the cylindrical portion 21 extending, in particular extending integrally, axially from the main portion 14 and the frustoconical portion 19, which in turn extends, in particular extends integrally, from the cylindrical portion 21.
  • the one cylindrical portion 20 and the other cylindrical portion 21 radially face each other, in particular they are parallel to each other when the cutting tooth 16 engages the groove 17.
  • the cylindrical portion 20 conveniently has an axial extension corresponding to the axial extension of the groove 17 and the cylindrical portion 21 has an axial extension corresponding to the axial extension of the cutting tooth 16.
  • This configuration ensures that the centring of the axes B and C and the tensioning of the sheet 4 take place before the cutting tooth 16 completes its stroke inside the groove 17, and, in any case, prior to the cutting of the packaging material.
  • a nominal cut of the sheet 4 is, thus, ensured.
  • the cutting body 13 is preferably provided with a handle 22, in particular coaxial to the axis C and extending from the opposite side of the main portion 14 to the peripheral portion 15, which facilitates the user's manipulation thereof.
  • the operation of the device 1 according to this invention will be described below, with particular reference to an initial condition wherein the base body 8 is arranged on a support plane and the sheet 4 is supported on the axial surface 12.
  • the user grasps the cutting body 13, initially separated from the base body 8, and overlaps it with the base body 8 itself, moving it towards the latter.
  • the frustoconical portions 18 and 19 slidably cooperate with each other, thereby determining the centring of the axes B and C and the tensioning of the sheet 4.
  • the cutting tooth 16 engages the groove 17, thereby determining the cutting of the sheet 4 and the creation of the membrane 2.
  • the reference number 1' represents a device for manufacturing membranes 2 according to an alternative embodiment of this invention.
  • the alternative device 1' differs from the device 1 in that the base body 8 comprises an additional groove 17' of the type described above and defining an additional recess in the raised portion 11 and arranged in a position radially distant from the groove 17.
  • the device 1' comprises a series of, in particular at least two, interchangeable elements 30' that can be alternatively, releasably coupled to the main portion 14 of the cutting body 13, coaxially to the axis C.
  • each interchangeable element 30' is defined by a circular plate body bearing a respective cutting tooth 16, 16' of the type described above extending axially from the respective plate body.
  • the cutting tooth 16 is arranged at a radial distance from the axis C different from the radial distance at which the cutting tooth 16' of the other interchangeable element 30' is arranged. These distances are measured when the interchangeable elements 30' are coaxially coupled to the cutting body 13; therefore, they refer to the axis C.
  • the cutting tooth 16 will be conveniently arranged at a radial distance such that it engages the corresponding groove 17 and the cutting tooth 16' will be arranged at a radial distance such that it engages the groove 17'.
  • the radial distance from the axis C of the cutting teeth 16, 16' corresponds to the radial distance from the axis B of the grooves 17, 17', respectively.
  • membranes 2 of a different format i.e. of a different diameter and, therefore, adapted for a different capsule format 3, by simply replacing the interchangeable element 30'.
  • the interchangeable elements 30' are preferably coupled to the cutting body 13 using clamping means, for example a screw 31'.
  • the user is able to carry out the above-mentioned centring of the axes B and C in a simple manner and without needing to worry about precisely coupling the base body 8 and the cutting body 13.
  • Such centring will determine, in use, the correct alignment between cutting body 13 and base body 8 and, thus, between cutting tooth 16 and groove 18, thus resulting in a cut of the sheet 4 under rating conditions.
  • the frustoconical portions 18, 19 therefore make the presence of an axial guide for the cutting body 13 superfluous, further simplifying the architecture of the device 1 and favouring its portability.
  • the interaction of the frustoconical portions 18, 19 causes, in addition, a tensioning of the sheet 4 radially outwardly, prior to the cutting of the sheet 4 itself.
  • the sheet 4 is, thus, tightly stretched and the cutting tooth 16 can penetrate it, and thus cut it, cleanly despite not having a cutting edge or blade.
  • the device 1 is, thus, less dangerous and, therefore, more portable (and/or pocket-sized).
  • the cutting tooth 16 could be borne by the base body 8 and the groove 17 could be borne, i.e. made, in the cutting body 13, with appropriate structural modifications.
  • the cylindrical portion 20 would have the same axial extension as the cutting tooth 16 and the cylindrical portion 21 would have the same axial extension as the groove 17.
