Abstract: In a method for making absorbent sanitary articles, each absorbent article includes a pair of side tabs fed from a single continuous tape divided by oblique cuts into first and second series of side tabs oriented in opposite directions. The side tabs of the first and second series are then fed along a first path and along a second path, respectively and are first rotated by 180° and then combined and transferred separately along a third, common path along which each tab of the first series has a respective tab of the second series placed alongside it to form a pair of side tabs. At least one of the side tabs of each pair is moved sideways such that each pair of side tabs is applied to a continuous web of material at a predetermined spacing.

Abstract: A device for processing a web of material for making nappies includes a rotary shaft having a first axis, a plurality of pads for receiving and holding the web. The pads are rotatable about the first axis and are movable relative to the first axis during operation. A plurality of anvils, each interposed between two consecutive pads, are connected with the rotary shaft and are rotatable with it about the first axis. A unit acting in conjunction with the anvils cuts the web into lengths. A first motor is mounted inside the device and connected to the pads to translate the pads along a radial direction at right angles to the first axis and a second motor is mounted inside the device and connected to the pads to rotate the pads about a second axis coinciding with the radial direction.

Abstract: An ultrasonic welding system and method for making welds on a strip made of polymeric material. The system includes a supporting structure, N welding equipment mounted thereon, and a processor. Each N welding equipment includes a pair of welding heads made of a sonotrode, including a sonotrode welding surface, and an anvil, including an anvil welding surface. One of the two welding heads is movable with respect to the other between a non-operating position and a welding position. A control member is operatively associated with the sonotrode and configured to vibrate the sonotrode at a nominal ultrasonic vibration frequency and to detect a current value of the vibration frequency. A vibration sensor is mounted on the movable welding head. The processor monitors the alignment condition between the sonotrode welding surface and the anvil welding surface by cooperating with the control member and with the vibration sensor.
