A continuous winding method produces a continuously wound electrical device, such an undulator. A continuous tape is wound about a series of turn around pins and in grooves in a magnetic core. A plurality of winding stacks are created, each transitioning to the next sequential stack by a transition tape portion extending from one turn around pin to the next turn around pin, which is position opposite with regard to the location of the pin on the magnetic core.

In one embodiment, a roll spindle comprises two roll supports and a differential.

Proposed is a friction shaft for a slitter that enables a winding pipe to stably roll unit materials formed by cutting a raw material, such as a raw fabric or film, with predetermined intervals, that can fix the rolling pipe even at a low pressure of compressed air, and that has a wide range of available rolling tension because the pressure range of compressed air that can adjust winding torque is wide.

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 temporary tape removal apparatus that includes: a chassis having fixed and guiding wheels; a boom arm extending outward from the chassis and being movable between up and down and side to side positions; a spool assembly including a rotatable spool for winding used temporary tape thereon mounted on the boom arm; and controllable drive means to rotate the rotatable spool. Using the apparatus to remove lane marking tape from pavements involves moving the temporary tape removal apparatus along a pavement having a length of lane marking tape thereon, and pulling the lane marking tape off the pavement by winding the tape onto the spool. Single lines of tape can be removed and multiple lines of tape can simultaneously be removed. The removed tape is spooled on disposable cores for disposal.

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.

Provided is an adhesive film production apparatus for producing an adhesive film having an adhesive layer on a base material layer, the adhesive layer having an elastic modulus at 230 C. of 1 MPa or greater and having a glass transition temperature higher than normal temperature, the adhesive film production apparatus including a feeding roller; a cutting part; and a plurality of winding cores, wherein the raw film of the adhesive film is wound on the feeding roller such that the adhesive layer faces outward, and wherein in the conveyance path of the adhesive film traveling from the cutting part toward the winding core, the number of times of the adhesive layer of the adhesive film bending in a convex manner is set to be equal to or more than the number of times of the adhesive layer bending in a concave manner.

A web processing apparatus comprising a web transport station and a web processing station. The web transport station comprises a web tension control assembly, which comprises a first tensioning device and a second tensioning device. Said first tensioning device is movably arranged for controlling tension of a first web. Said second tensioning device is movably arranged for controlling tension of a second web independently of the tension of the first web. Said first tensioning device comprises a first interior space and the first tensioning device is arranged with respect to the second tensioning device such that the first interior space at least partly accommodates the second tensioning device. The web processing apparatus allows for accurately controlling tension of the first and second webs simultaneously and independently of one another in a tandem mode, while maintaining the possibility for controlling tension of a single web in a single mode.
