The disclosed subject matter provides a mandrel feeding device and a battery winder. The mandrel feeding device has a dispensing station, an adjusting station, an adhesive application station, a transferring unit, a dispensing unit, a feeding unit configured for gripping a mandrel on the transferring unit and transferring gripped mandrel to a winding mechanism.

A sheet supply device includes a supporter, a rotation device, a guide, a support shaft, a biasing member, a sensor, a roller, and control circuitry. The sensor is disposed to protrude from the facing portion toward the roll and biased in a direction to contact the outer peripheral surface of the roll. The sensor outputs a detection signal at a level corresponding to an amount at which the sensor protrudes from the facing portion. The roller is supported by the facing portion, to contact the outer peripheral surface of the roll at a position different from a position of the sensor in a circumferential direction of the roll. The control circuitry controls the rotation device based on a signal change rate that is a change amount of the level of the detection signal per unit time. The control circuitry causes the rotation device to rotate the spool in the winding direction, and stops an operation of the rotation device when the signal change rate based on a change in relative positions between the outer peripheral surface and the sensor without passage of a leading end of the sheet through the position of the sensor does not exceed a predetermined reverse set threshold value.

The present application relates to apparatus for stretch wrapping goods with stretch wrap film including: a film roll carriage for dispensing at least one band of film from at least one stretch wrap film roll core, a roping mechanism for roping the at least one band of film by edging at least one lateral side edge of the film, a pre-stretcher for pre-stretching the film by passing the roped film through a pre-stretcher, a stretch wrap carousel for wrapping the roped and pre-stretched film around the goods, wherein the at least one band of film is passed through the roping mechanism prior to the pre-stretcher.

A cassette unit is provided and comprises i) a supply roller, ii) a receiving roller, iii) a dispensing edge, and iv) a dispenser material strip comprising a multiplicity of adhesive elements arranged on a strip-type separation material, wherein the dispenser material strip is partially wound on the supply roller and fastened at one end to the receiving roller, the strip-type separation material is guided around the dispensing edge, between the supply roller and the receiving roller with respect to the strip direction, the strip-type separation material is guided around the receiving roller, or around the part of the strip-type separation material wound on the receiving roller, in front of the dispensing edge with respect to the strip direction, such that the receiving roller, or the part of the strip-type separation material wound on the receiving roller, acts as a deflection element for deflecting the dispenser material strip.

An atomization substrate assembly includes: a strip-shaped substrate; and a housing assembly having a housing provided with a housing space for housing the strip-shaped substrate and including a first housing and a second housing, one of the first housing and the second housing being provided with an opening for placing the strip-shaped substrate into the housing space, and an other one of the first housing and the second housing being arranged on the opening in a covering manner.

This application relates to a winding and unwinding apparatus and a preparation system of electrode plate. The apparatus includes supports, a rotating shaft, a rotating turret, and a power assembly. The rotating shaft is rotatably disposed on the support. The rotating turret is disposed on the rotating shaft and capable of rotating along with the rotating shaft so as to switch between at least two target operation positions. The power assembly includes a first power source and a magnetic powder clutch. The rotating shaft and the first power source are in transmission connection with each other via the magnetic powder clutch. The magnetic powder clutch is configured to control the rotating shaft to remain stationary when the rotating turret is hovering at each target operation position.

The electrode driving apparatus is for driving an electrode that is coated with an active material, and includes a main base, a sub base spaced apart from and parallel to the main base, a shaft extending from the sub base toward the opposite side to the main base, an electrode driving roller that rotates about the shaft and is in contact with the electrode, and a position adjuster that is located between the main base and the sub base and regulates a gap between the main base and the sub base.

A machine comprises a pick and place stage and includes a plurality of releasable connectors.

A support material is wound over rollers onto a storage roller or spool. The backing support material provides a substantially flat surface upon which a sheet of flexible material is placed by the pick and place stage.

The sheet of material and the backing support material are then wound onto the storage roller or spool which may be removed for storage and/or transportation.

Delicate sheets of pieces of flat material, such as carbon fibre, may thus be protected from damage during handling, storage and transportation that may otherwise result in damage to the material.

The process is reversed to lay down the material, for example into a mould, during manufacture of, for example, an aeroplane wing.

A System and Method for Adaptive Paper Web Winding that adjusts Operational Parameters, including torque, pressure, tension, acceleration, Jerk Rate, and sheet speed, in response to Operational Data and feedback. The system, in one embodiment, comprises a Front Drum with adjustable torque control, a Rider Roll with variable pressure regulation, an Unwind Section with tension control, and a Control Unit configured to maximize coupling between drive rolls and driven built paper roll. The method involves detecting the Coefficient of Friction of a Paper Web, then adjusting Operational Parameters in response to Operational Data and feedback. This invention improves efficiency and reliability in paper winding operations by automating adjustments to accommodate variations in the Coefficient of Friction of a Paper Web.
