A feeding unit to feed a component in an automatic manufacturing machine, which has at least one holding head designed to receive and hold the component; a conveyor to cyclically move the holding head along an application path; and a rotation station arranged along the feeding path and in which the holding head rotates relative to the equipment and around a rotation axis to vary the orientation of the component. The conveyor has a closed curve guide arranged in a fixed position along the application path; and an equipment supporting the holding head and provided with at least one slide coupled to the guide so as to freely slide along the guide. An actuation system controls rotation of the holding head around the first rotation axis and has a cam and a cam follower roller, which can be coupled to the cam and mechanically connected to the holding head.

A feeding unit to feed components in an automatic manufacturing machine; the feeding unit has: a plurality of sucking holding heads, which are each designed to receive and hold a corresponding component; a closed curved guide, which is arranged in a fixed position along the application path; a plurality of equipment, each supporting a corresponding holding head and provided with at least one slide, which is coupled to the guide so as to freely slide along the guide by means of a plurality of wheels; a suction chamber, which is mounted so as to rotate around a rotation axis; and a flexible connection system, which pneumatically connects the suction chamber to each holding head.

The disclosure discloses a cutting apparatus including a movable blade and a guide device. The movable blade is configured to move along a sliding direction to a cutting position. The guide device includes an upper guide part including a contact part and a lower guide part including at least one guide surface. The contact part is disposed at a position separated from a first blade edge of the fixed blade by a first distance in the transport direction and by a second distance in an upper direction. The at least one guide surface that inclines in an inclination direction in which the at least one guide surface inclines downward at a predetermined angle toward a downstream in the transport direction and is disposed to have an interval of a third distance against the contact part in a direction orthogonal to the inclination direction.

Each of a first rotary blade and a second rotary blade includes a rough surface portion and a smooth surface portion. The rough surface portion has a predetermined width from a blade edge at its circumferential edge portion and has an arithmetical mean roughness of greater than 0.5. The smooth surface portion is provided radially inward of the rough surface portion and has an arithmetical mean roughness less than the arithmetical mean roughness of the rough surface portion.

A separator cutting apparatus includes: a fixing part configured to fix temporarily the electrode assembly; a cutter supporting part disposed above the fixing part; a cutter part disposed below the cutter supporting part, and configured to cut a separator among the electrode assembly temporarily fixed to the fixing part; and a spring part configured to connect elastically the cutter supporting part and the cutter part to each other, and return the cutter part to an initial position after cutting the separator; the spring part includes a spring bush coupled to a supporting shaft provided in the cutter supporting part and the cutter part, respectively, a spring holder integrally coupled to the spring bush, and a spring that expands and contracts according to the elevation of the cutter part by coupling both ends to the spring holder, and the spring holder and the spring bush are made of a non-metallic material.

The present disclosure is directed to a process and an apparatus for cutting a continuous rubber-covered belt in a process for building tyres for vehicle wheels, wherein the apparatus comprises a cutting group, in turn comprising: a knife formed by a first half-part and a second half-part and movable along a cutting direction that is tilted with respect to a supply direction of a rubber-covered belt placed beneath the knife. The process comprises: lifting a lifting element placed below the continuous rubber-covered belt and at the cutting zone, until a portion of rubber-covered belt is lifted, and lowering the single first-half part of the knife, making it slide with respect to the second half-part.

A cutting device includes a fixed blade and a movable blade that slides with respect to the fixed blade during cutting, the movable blade having a first end that engages with the fixed blade at cutting start and a second end that engages with the fixed blade at cutting end, an urging member connected to the movable blade to urge the movable blade towards the fixed blade and a rotation of the movable blade in a first rotational direction, and a support for the movable blade having a shaft that rotates as the movable blade moves, the shaft having a center portion and first and second ends rotatably connected to the movable blade, wherein points of connection of the first and second ends are at locations that urge a rotation of the movable blade in a second rotational direction opposite the first rotational direction.

The invention relates to a method for successively winding a film web onto a plurality of spools, wherein the film web is wound to form a first spool, and a tube and/or winding shaft for forming a subsequent second spool and the film web are moved closer to one another and/or are brought into contact with one another upstream of the first spool. The film web is cut, and thus an end of the film web is produced, with end is wound onto the first spool, and a new start of the file web is produced, which is wound onto the second tube. In order to cut the film web, the film web is cut partially in the transverse direction, at least one cut edge and at least one uncut region remaining in the transverse direction, the uncut region being subsequently torn off or cut off.

An apparatus and method for splitting a high filament count carbon fiber tow into a set of tows with reduced filament counts. The apparatus is comprised of an electrolyte bath assembly and a splitting assembly comprised of at least one blade. The preferred embodiment of the blades being Polytetrafluoroethylene (PTFE). The splitting assembly being positioned within the electrolyte bath or adjacent to the exit of the electrolyte bath.
