A sonotrode comprising: a head defining a sealing surface elongated along a first direction; and a first and a second drive unit distinct from one another, each comprising at least one piezo-electric element; wherein first and second drive unit may be electrically fed by an unique generator to cause oscillation of head; the height of head measured along a second direction transversal to sealing surface being substantially equal to half the wavelength of wave oscillating in second direction; at least one slot extending through head transversally to first and second direction; a finite number of nodal points at which amplitude of oscillation of head is substantially equal to zero; and a plane on which at least some nodal points lie and which divides head in a first portion and second portion; the slot extends completely within one only between first and second portion and at a certain distance by plane.

An induction sealing device for producing packaged pourable food products from heat-seal sheet packaging material. The sealing device has a signal source, an inductor, and an impedance matching circuit connected between the signal source and the inductor. The impedance matching circuit has: two input terminals; a first and second line connected to the input terminals; a variable-capacitance stage having capacitive modules each made up of a capacitive element and a controlled switch; and a control stage to control the controlled switches. Each controlled switch includes: input terminals receiving a respective control signal from the control stage, with one input terminal of each controlled switch connected to the second line; a single two-way controlled switching element having a control terminal connected to the other input terminal of the controlled switch; a first current-conducting terminal connected to the first line, and a second current-conducting terminal connected to the second line.

Induction sealing device for producing pourable food packages

An induction sealing device which may be used for producing packages of pourable food products by transversely sealing a tube of sheet packaging material having at least one layer of induction heatable material covered with plastic material. The sealing device has: a generator for generating an alternating power signal; an inductor receiving the alternating power signal to induce a parasitic electric current in the layer and locally melt the plastic material to form a transverse seal; and a matching circuit for achieving optimum power transfer between the generator and the inductor. The matching circuit includes an inductive-capacitive circuit, in which the capacitance of a variable capacitance capacitive element is adjustable so that the current-voltage phase angle is close to zero.

Induction sealing device and method which may be used for producing packages of pourable food products

The method is aimed at indirectly determining the energy absorbed by a conducting layer ( ) forming part of a strip of packaging material ( ) to be sealed transversely. The method is based on measuring parameters correlated with the power supplied by a current source ( ) to the packaging material ( ) during sealing, and with the temperature of the conducting layer ( ). The temperature measurement takes into account the temperature of the product to be packed, the characteristics of the packaging material, and the characteristics of the mechanical sealing members; correct cutting of the packaging material after sealing is also determined; and the parameters are monitored by measuring associated quantities and by comparison with permissible values.
