A continuous wire drive system for a needleless electrospinning apparatus, the electrospinning apparatus including an electrospinning enclosure and within which a nanoscale or submicron scale polymer fiber web is formed onto a substrate from a liquid polymer layer coated onto a plurality of continuous electrode wires passing through the electrospinning enclosure. The continuous wire drive system includes a master wire drive drum and a slave wire drive drum, each of the master wire drive drum and slave wire drive drum including a plurality of wire guides, each of the wire guides including a channel or groove for receiving one of the plurality of continuous electrode wires. The continuous wire drive system is external to the electrospinning apparatus, and the continuous wire drive system drives the plurality of continuous electrode wires through the electrospinning enclosure.

The present disclosure refers to a method and a system for tracking cable drums and length of cable on the drum. A method includes attaching a tracker device with a tracker identifier to a cable drum with a drum identifier, said drum identifier being associated in a database with drum dimensions and with cable dimensions of a cable stored on the drum. The method includes associating in the database the drum identifier also with the tracker identifier. The method includes when an event comprising at least a shock and/or a number of rotations of the cable drum around a longitudinal axis occurs, activating a first electronic circuit of the tracker device including a sensing device that detects at least the event, storing the detected event in a local memory of the tracker device and switching the first electronic circuit to standby mode after the detected event is stored.

In one aspect, the present disclosure is directed to a dispenser assembly for dispensing supplies of sheet material. The dispensing assembly can include a carrier supporting the supplies of sheet material and being moveable along a track between various dispensing positions. The dispenser assembly also can include a carrier pivoting assembly with a lever that engages one of the supplies of sheet material and rotates during dispensing thereof, as well as one or more biased pins connected to the lever and configured to engage locking features provided along the track to support the carrier in one of the dispensing positions. The biased pins further can be configured to retract with rotation of the lever such that they disengage the locking features so the carrier to moves along the track to different dispensing position. Other aspects also are described.

An automated product dispenser for dispensing a product from a supply of product is provided. The automated product dispenser includes a chassis assembly, a drive assembly, and an isolation member. The chassis assembly includes a chassis frame, and the drive assembly includes a motor, a drivetrain, and a drivetrain housing. The isolation member mounts the drive assembly to the chassis assembly such that the drive assembly is substantially spaced apart from the chassis frame. A related method of inhibiting vibration transmission in an automated product dispenser also is provided.

The static charge eliminator includes a charger including one or more charging units, and a grounded needle-shaped conductor. The charger is configured to charge an insulating film such that the absolute value of the surface potential of the insulating film is 3 kV or more. The needle-shaped conductor is arranged to generate a corona discharge between the needle-shaped conductor and the insulating film charged by the charger. Thereby, the static charges on the insulating film can be reliably eliminated.
