The invention relates to a homogenized tobacco sheet production line comprising: A tank (501) adapted to contain a slurry formed by a tobacco powder blend, a binder and an aerosol former in an aqueous medium; A cast apparatus (600) adapted to receive slurry from the tank and to cast the slurry so as to form a homogenized tobacco material; A movable transporting support (606) on which said slurry is casted and adapted to transport the homogenized tobacco material along a transport direction; A slitter (611) located downstream the cast apparatus adapted to slit the homogenized tobacco material along the transport direction so as to form portioned homogenized tobacco sheets; and A winding station (613) located downstream the slitter adapted to receive the portioned homogenized tobacco sheets from the slitter and to wind at least one of the portioned homogenized tobacco sheets in a bobbin. It also relates to a method for inline production of a homogenized tobacco sheet.

A friction shaft for a slitter has winding tubes disposed on an outer surface thereof to roll unit materials formed by cutting a raw material such as various kinds of paper, fabric, or film with predetermined intervals. The friction shaft includes a first rotary shaft, tubes, lug bodies for torque, first fixed shafts, brake pads, a second rotary shaft, guide members, lug bodies for clamping, second fixed shafts, a plurality of lug rollers, covers, a first elastic member, and second elastic members.

A core member is provided for storing shrink film. The core member includes a plurality of rollers, each having a disc and a core extending upwardly from the disc. The plurality of rollers are aligned longitudinally along an axis and laterally along a plane. The plurality of rollers are rotatable to wind the shrink film about the rollers.

A device for removing road tape from a surface comprises a body, and a drive assembly coupled to the body. The drive assembly comprises a motor having a drive wheel, at least one drive belt, a rolling drum drive wheel configured to engage the at least one drive belt, and at least one rolling drum configured to secure an end of the road tape. The rolling drum is configured to rotate in response to rotation of the rolling drum drive wheel and wind the road tape about a circumference. The winding of the road tape drives the body in a forward direction.

In one example, a device for unwinding or winding multiple rolls of print substrate includes multiple spindles each to hold a roll of print substrate and a differential operatively connected to one end of each spindle. The spindles are aligned with one another lengthwise along a spindle axis and the differential is to output torque along a differential axis offset from the spindle axis to turn the spindles on the first axis.

A method for arranging elongated elements to be used in a process for building tyres for vehicle wheels, including: winding in parallel a first elongated element and a second elongated element of a first type respectively on a first winding support and a second winding support coupled and rotatable about a first rotation axis; winding in parallel a third elongated element and a fourth elongated element of a second type respectively on a third winding support and a fourth winding support coupled and rotatable about a second rotation axis, where the elongated elements of the second type are different from the elongated elements of the first type; decoupling the second winding support from the first winding support and the fourth winding support from the third winding support; and coupling the second winding support with the third winding support and the fourth winding support with the first winding support.

A paperboard carrier suitable for use with textiles may include one or more strips of paperboard secured together to form a hollow tubular body, the body having an outer surface, and a coating covering some or all of the outer surface. The coating comprises a coating agent such as a silicon resin dispersed in a solvent such as isopropyl alcohol and little or no water. The coating may be applied to the outer surface by using a plurality spray nozzles arranged axially or circumferentially about the carrier.

The present invention relates to a device (20) for winding a longitudinally cut material web having multiple longitudinal strips (12) on a plurality of winding tubes (16) to form in each case a wound roll. The device comprises an axle (24) and, mounted on the axle, a plurality of ring-shaped winding drives (22) that are individually controllable in their operating position. Each winding drive (22) forms an external-rotor electric motor and comprises a static interior tube (40) and a rotatable external tube (50). The external tube (50) that is rotatable on the rolling bearings (48) bears, on its interior, a device for providing an excitation magnetic field (52) that forms the external rotor of the electric motor.
