The present disclosure concerns apparatus and methods for reinforcing composite materials by insertion of reinforcement pins. Example embodiments include an apparatus for reinforcing a composite preform, comprising: a carriage for introducing reinforcement pins into the composite preform, the carriage comprising a drill module, a pin feeder module and a tamper module, the assembly being translatable relative to the composite preform, wherein the drill module and pin feeder module are exchangeable between a common actuation position on the carriage.

The invention relates to a sealing bar for a vacuum drawer for vacuuming food, having a base support which comprises at least one welding wire extending in the longitudinal direction over the surface, with the welding wire being fastened to the base support by means of a clamping connection at one side or at both sides.

A method is described for opening a heat bonded sterile connection that includes a skin of material blocking flow between the connection site. The method includes applying external pressure to the connection site.

A welding device for making and hermetically sealing at least one package containing a product, comprises first and second sealing and cutting equipment. Each sealing equipment is configured to receive a film forming a tubular envelope, to seal and cut it transversally for making at least one package. The welding device comprises a support body, bearing the first and the second sealing and cutting equipment, which is connectable to a packaging machine preferably a rotary drum of a packaging machine. Each sealing and cutting equipment comprises an arm operating as a sealing and cutting head and an abutment body. The arm is rotatably constrained to the support body and reversibly movable between an active position substantially abutting the abutment body, and an inactive position raised with respect to the abutment body. A locking device locks the arms in the active position in the welding step.

A buttress assembly is configured to temporarily adhere to a wet surgical stapler end effector. The buttress assembly includes a buttress body and a humidity tolerant adhesive material. The humidity tolerant adhesive material is applied to at least one side of the buttress body. The humidity tolerant adhesive material is configured to hold the buttress body to an underside of an anvil or a deck of a staple cartridge for at least five minutes in an environment of 100% relative humidity at approximately 37 C.

A molding apparatus for a loop structure includes a molding die within which both ends of an elongated structure are located in such a manner that the ends are in contact with each other, the elongated structure being formed of a rubber to which a peroxide cross-linking agent is added; a liftable housing including a lower part having an opening, the housing defining a containment space within which the molding die and the elongated structure are located when the housing is lowered; a degassing device configured to depressurize and degas the containment space; a heating device configured to heat the molding die in the containment space; a pressure device configured to pressurize the ends of the elongated structure with the use of the heated molding die in the containment space to proceed cross-linking reaction of the rubber, thereby bonding the ends of the elongated structure; and an elevating device configured to lift and lower the housing.
