A method and apparatus for making pouches is disclosed. It includes using one or more of the following features: using two servo motors to drive a platen, providing a calibration routine is run at start-up and/or after the machine has been operating; controlling in response to feed back from the servo motor(s) such as feedback indicative of the distance the platen travels; the feedback is not of force exerted by the platen; and/or the platen is controlled to prevent unacceptable fracturing of the film laminate.

A method for welding profiled elements in plastic material, includes the steps of: preparing two profiled elements, arranged with respective zones to be facing one another; making a groove in correspondence to at least one zone, by a removal operation on a peripheral edge of at least one profiled element; heating the zones to be welded; coupling the zones to be welded to one another, pressing the profiled elements one against the other so as to keep the zones to be welded in reciprocal contact. The coupling step includes: melting the zones to be welded into one another in order to define a welding bead; making a containing compartment defined by the groove, the welding bead being made internally of the containing compartment; and arranging a containing presser in correspondence to the containing compartment for preventing exit of the welding bead from the compartment itself.

Various embodiments of a bonding machine structured and programmed for bonding or laminating one or more materials is disclosed. In one embodiment, the bonding machine comprises a support bar and one or more bonding arms movably coupled to the support bar. Each of the bonding arms may include a heating bar including one or more heating elements, and an actuator configured to provide movement of the bonding arm between the support bar and a material to be processed. At least one of the bonding arms may be programmed to operate with a temperature setting, pressure setting, application timing setting, timing sequence setting, or center position setting which is independent of at least one of the other bonding arms.

A product including two or more plies with each ply including one absorbent layer and a second opposing fluid impervious layer. The two plies are arranged such that the fluid impervious layers face each other and are positioned at the inside of the two-ply product. The two plies are bonded on two or three sides to form a sleeve or a pocket, such that a hand can be inserted between the two plies and positioned in contact with one or both fluid impervious layers. In this manner, the product is absorbent on both sides, and can be utilized on both sides while preventing hand contact with the material absorbed or picked up by the product.

A single facer machine is disclosed which comprises a first corrugating unit having a pair of upper and lower rolls, a second corrugating unit also having a pair of upper and lower rollw, and a common pressure roll disposed in operative association with both the first corrugating unit and the second corrugating unit. The single facer machine is characterized in that either of the combination of the first corrugating unit and the pressure roll or the combination of the second corrugating unit and the pressure roll is selectively operated to form a single-faced corrugated board.

AN APPARATUS AND TECHNIQUE FOR ENCAPSULATING A PRINTED WIRING ARRAY WHEREIN THE CONDUCTORS ARE DISPOSED UPON THE EXPOSED SURFACE OF A FLEXIBLE SUBSTRATE, THE ENCAPSULATING COVERLAY BEING A FLEXIBLE COVERLAY OR COVERING FILM HAVING A SURFACE ARRANGED TO ESTABLISH A BOND WITH THE EXPOSED SURFACE AND CONDUCTORS. THE APPARATUS AND TECHNIQUE INCLUDES A MEANS FOR ESTABLISHING A NIP ZONE BETWEEN FIRST AND SECOND PRESSURE MEMBERS, SUCH AS ROLLERS, AND FURTHER INCLUDES MEANS FOR DELIVERING A PRINTED WIRING WHICH IS MOUNTED ON A SUBSTRATE AND A FLEXIBLE COVERLAY FILM FOR THE MOUNTED WIRING INTO THE NIP ZONE SIMULTANEOUSLY. IN ADDITION, AT LEAST ONE OF THE PRESSURE MEMBERS IS PROVIDED WITH A RAISED RETICULATE PATTERN (OF SUBSTANTIALLY CONTINUOUS CONFIGURATION) HAVING INTERSECTING LONGITUDINAL AND TRANSVERSE RECESSED SEGMENTS SO AS TO FORM A PLURITY OF SUBSTANTIALLY ISOLATED AND CLOSED TACK BONDED ZONES EXISTING BETWEEN THE EXPOSED SURFACE AND THE BONDING SURFACE. THE TACK BONDED MATERIAL MAY THEREAFTER BE FIRMLY BOUNDED TOGETHER OVER THE ENTIRE AREA OF CONTACT.
摘要:
A bonding apparatus for bonding a flexible member to a curved member in the atmosphere while preventing air bubbles from entering between the members includes a bonding stage for holding a first member with an inside surface facing up, a flexible carrier sheet for holding a second member with a bonding surface facing the inside surface of the first member, and a moveable bonding roller disposed above the carrier sheet. A control portion causes the bonding roller to move down so that the carrier sheet is depressed into a V-like shape, whereby a portion of the second member is bonded to the first member preceding the remaining portion of the second member, and thereafter, the bonding roller is caused to move along the curved shape of the first member to bond the remaining portion of the second member to the first member.
