A composite structure is fabricated by laying up at least one ply of fiber reinforcement and at least one layer of resin on a tool. The resin film layer is formed by laying strips of resin film. The fiber reinforcement is infused with resin from the resin layer.

A device for welding profiled elements in plastic material includes: a base frame supporting retaining members of respective profiled elements, to engage the profiled elements with corresponding zones to be welded facing one another; a heater for heating the weld zones of the profiled elements; a unit to move the retaining members, to shift the profiled elements between a first reciprocal away direction and a second reciprocal closer direction wherein the zones to be welded are coupled together; and a removal unit utilizing milling The removal unit includes: a supporting frame positioned in correspondence to the retaining members; at least one machining tool; a motor part associated with the tool; and a movement member of the tool, to move it between a first idle condition and a second working condition wherein it is placed between the profiled elements.

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.

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

A rotary die system that includes first and second axially aligned, coacting rotary dies positioned adjacent one another. Each die includes a working surface having a plurality of recesses defined therein. The recesses in the first die are each configured to align with a recess in the second die to form a product cavity upon coaction of the first and second dies. The product cavity is configured to receive a product. Each recess in at least one of the first or second dies includes a pin therein that is configured to puncture a film that at least partially surrounds the product.

A composite structure is fabricated by laying up at least one ply of fiber reinforcement and at least one layer of resin on a tool. The resin film layer is formed by laying strips of resin film. The fiber reinforcement is infused with resin from the resin layer.

An active anvil assembly for use in forming a looped suture is provided. The active anvil assembly includes an anvil member, a first sensor operably connected to the anvil member, and a control assembly. The first sensor is configured for measuring at least one of force, torque, and distance feedback. Also provided are systems and methods for forming a looped suture including an active anvil assembly.

Composite tape is laminated onto a substrate using a gantry to move a tape laminating head along the length of the substrate. The laminating head is mounted for movement along a beam on the gantry that extends across the width of the substrate. The direction of lamination may be altered by changing the angular orientation of the beam.
