A system for determining an amount of stretch film unwound from a stretch film dispensing apparatus. The stretch film dispensing apparatus includes a roller, from which the stretch film can be unwound, at least one supply roll sensor positioned relative to the roller to sense a distance from the at least one supply roll sensor to an outside face of a supply roll on a core on the roller, and a controller. The controller is configured to determine the amount of stretch film unwound based on the one or more signals provided by the at least one supply roll sensor.

A coating film transfer tool may include a casing that houses a feeding reel around which a transferable tape is wound and a winding reel; and a transfer head having a main body portion arranged in a front side which is one side of a front-rear direction of the casing to extend in a left-right direction perpendicular to the front-rear direction in a front end portion and provided with a pressing edge portion adapted for transferring the coating film to a transfer target surface. The casing or a base member housed in the casing may have a protruding tip that extends to the transfer head side and is connected to the transfer head. The protruding tip may press a part of an area including a center of the left-right direction of the main body portion to the transfer target surface side in the event of a transfer.

A tensioning control device having a first motor that applies a torque to a first end of a substrate in a first direction and a second motor that applies a torque to a second end of the substrate in a second direction that is generally opposite the first direction is disclosed. In this manner, the first motor and the second motor apply torque to the substrate in opposing directions, thereby placing the substrate in tension. In one embodiment, the first motor applies a torque to the first end of the substrate that is equal to the torque applied to the second end of the substrate by the second motor. By placing the substrate in tension in this manner, an actuator is able to incrementally move the substrate in a forward direction and a backward direction independent of the tension applied to the substrate.

An apparatus includes a first drive unit configured to rotate a roll sheet supported by a roll support unit in a predetermined rotation direction to feed the sheet into a conveyance path, an abutment portion provided so as to be capable of abutting against an outer peripheral surface of the roll sheet at a first position, and a rotation member provided so as to be capable of abutting against the outer peripheral surface at a second position. The first drive unit rotates the roll sheet in the direction to introduce, into the conveyance path, a leading edge of the sheet having passed between the first and second positions. The apparatus further includes a second drive unit configured to rotate the rotation member in a direction in which a slack of the sheet is formed between the first and second positions.

An upstream drive roller transports an elongate medium. An upstream tension sensor detects tension of the medium. A downstream drive roller transports the medium. A downstream tension sensor detects tension of the medium in a position between the upstream and downstream drive rollers. A control unit controls transportation of the medium by operating the upstream drive roller based on a first difference which is a difference between a first detection value and a target value, operating the downstream drive roller based on a second difference which is a difference between a second detection value and a target value, and when a specific condition is satisfied, further operating the downstream driver roller with an adjustment value, which is based on the first difference, added to the second difference.

An adhesive tape dispensing device with a tape alignment mechanism, comprising a body formed from a rigid material or materials, configured to hold and dispense adhesive tape, and a tape alignment mechanism comprising at least one spring that presses laterally against the edge of the tape, the side of the tape form, or against a hub onto which the tape is mounted, wherein one edge of the portion of tape being dispensed is kept in a fixed alignment relative to the dispensing device while it is being dispensed.

At least one jack screw from a tape deck base may be removed. The tape deck base may be below a rigid support base that includes a rigid support shaft in the center of the rigid support base. A piezoelectric stack may be inserted where the at least one jack screw was removed from the tape deck base. The piezoelectric stack may tilt a tape guide roller bearing in a skew direction to improve the motion of tape in a tape path.
