Patent number: 7222472Abstract: Wrapping material utilized by a packaging machine is advanced along a set feed path through a station where an accessory material, typically adhesive, is applied in spots to selected areas of the surface, whereupon the material is charged electrostatically at a first station, and thereafter sensed at a second station to reveal the distribution of the charges; the electrostatic charges register more strongly on and around the spots, so that by measuring any variation in strength relative to the remainder of the surface, identifiable with faulty application of the adhesive, substandard material can be detected before it reaches the wrapping stations of the machine.Type: GrantFiled: August 8, 2003Date of Patent: May 29, 2007Assignee: G.D S.p.A.Inventors: Mario Spatafora, Bruno Tommasini

Patent number: 7220088Abstract: A toolhead for use on a multi-axis machine tool consists of a support assembly equipped with a pivoting spindle designed to accept a removable tool-holder, and centered on a machining axis about which a tool clamped to the tool-holder can be driven in rotation. Also forming part of the toolhead is a depth stop affording an active surface substantially transverse to the machining axis and positionable against a surface of a workpiece. The depth stop is mounted to the support assembly and capable of movement along the machining axis between a first position, distanced from the spindle, and a second position of proximity to the spindle. Transducers incorporated into the toolhead are able to sense the position of the active surface relative to the support assembly, and thus used to control the depth to which the workpiece is penetrated by the tool.Type: GrantFiled: April 15, 2005Date of Patent: May 22, 2007Assignee: JOBS S.p.A.Inventors: Maurizio Ferrari, Sandro Foletti
