A method for manufacturing a high-pressure tank including a reinforcing layer in which rims of both ends of a tubular member and rims of a pair of dome members are joined to overlap each other in a radial direction includes producing the dome members and producing the tubular member. The producing of the dome members includes producing a wound body on a mandrel, curing a resin contained in the wound body, shaving the wound body after the resin is cured to reduce, toward a split line, thicknesses of the rims of the dome members to be obtained by splitting the wound body, splitting the shaved wound body into the dome members by cutting the wound body along the split line, and demolding the dome members from the mandrel.

A transverse cutting system for a machine for the production of plastic film includes a supporting structure carrying a cutting unit, which are moved between a rest position away from a path of a plastic film being wound and an operating position along the path of the plastic film; a rotating support carrying a hot wire; a rotating cap, associated to an idle roller and arranged transversally to the path of the plastic film that is moving forwards, and an actuator, which controls the rotation of the rotating support carrying the rotating cap and causes the rotating cap to interfere with the plastic film before the hot wire also interferes with said plastic film. The same plastic film, owing to the friction force generated by the rotating cap, entrains it with it, causing the rotating cap to equalize the linear velocity of the plastic film.

A bioresorbable, implantable device having controlled drug delivery is disclosed herein. The bioresorbable, implantable device is configured as a film, a roll, a tube, and a stent. The bioresorbable, implantable device is configured to release an active ingredient (the “drug”) from the bioresorbable, implantable device when the bioresorbable, implantable device is implanted within a body. The bioresorbable, implantable device is configured to control the onset of the release of the drug, the sequence of drug delivery, and the duration of drug delivery by embedding the drug within at least one therapeutic layer positioned within bioresorbable, implantable device.

A multilayer bioresorbable stent having sustained drug delivery is disclosed herein. The bioresorbable stent releases a therapeutic substance from the body of the bioresorbable stent starting when the bioresorbable stent is implanted within an anatomical lumen and ending when the entire mass of the bioresorbable stent is no longer present within the anatomical lumen. The bioresorbable stent releases the therapeutic substance gradually during the treatment as the mass of the each layer of the bioresorbable stent erodes. Methods of making the therapeutic layers within the bioresorbable sent are further disclosed. Sustained drug delivery reduces the risk of late and very late stent thrombosis.

A method for manufacturing a part made of composite material. The method is performed by a system providing a mandrel around which a composite material is wound, and a reel around which a strip of the composite material comes to be wound.

A system for manufacturing bags with counting marks includes a workstation for making bags, and a coding machine for spraying counting marks on the bags. The coding machine includes a main body, a fixing structure and a spraying gun. The main body has ink cartridges for providing ink and a pressure mechanism to spray the ink through the spraying gun. The spraying gun is fixed to a fixing structure and connected to the main body via a cable such that the ink of the ink cartridges is operably moved from the ink cartridge to the spraying gun via the cable. The cable includes channels, each channel adapted for delivering a respective color of the ink. The spraying gun includes nozzles coupled to the channels for spraying the ink on the bags so as to form the counting marks thereon.

A wrapped V-belt includes: a belt main body containing a compression layer containing a compression rubber layer and a fabric-laminated body layer a tension rubber layer and a tension member buried between the compression layer and the tension rubber layer; and an outside cloth that covers a periphery of the belt main body, in which the compression layer has a plurality of notch portions not covered with the outside cloth, and the notch portion has a top disposed in the fabric-laminated body layer.

Disclosed herein is a method for filament winding. The method includes bonding a veil material to the unidirectional fabric to veil-stabilize the unidirectional fabric. The method also includes slitting the veil-stabilized unidirectional fabric to separate a veil-stabilized fabric portion. The method also includes directing the veil-stabilized fabric portion to an application head. The method also includes winding the veil-stabilized fabric portion on a winding mandrel.
