A method for arranging elongated elements in a process for building tyres for vehicle wheels, including: simultaneously winding a first elongated element and a second elongated element respectively on a first winding support in a first axial position and on a second winding support in a first axial position; simultaneously winding a third elongated element and a fourth elongated element respectively on the first winding support in a second axial position different from the first axial position and on the second winding support in a second axial position different from the first axial position, in which the elongated elements of the second type are the same as each other and different from the elongated elements of the first type.

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.

The present invention relates to a film wrapping machine for a product packing device using a stretch film, including a frame having vertical bars extending upward and spaced apart from each other, a film clamping unit including a pair of suction pads which are moved in a direction of being spaced apart from each other in a state of adsorbing the stretch film so that a front end portion of the stretch film supplied from a film supply device is opened, and a plurality of clamps configured to grip the front end portion of the stretch film opened by the suction pads, receive the stretch film whose upper end is cut and bonded by the film supply device in a wrinkled state, and process the stretch film to be covered on a product in a process of lowering the vertical bars, and a controller which controls operation of the film clamping unit and the film supply device.

A method for arranging elongated elements in a process for building tyres for vehicle wheels, including: arranging a first winding support with a first elongated element of a first type wound on the first winding support; arranging a second winding support with a second elongated element of a second type different from the elongated element of the first type wound on the second winding support; arranging a coupling device including a first coupling body and a second coupling body rotatable with respect to one another about a rotation axis; and arranging the first winding support on the first coupling body and the second winding support on the second coupling body.

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 film wrapping apparatus includes a shaft member having two holding portions coaxially aligned with each other, a roll locker for releasably locking two film rolls at the holding portions respectively in a free-rotating manner, and a dispensing handle transversely extended from the shaft member at a position between the holding portions thereof, wherein the dispensing handle provides a holding point for being held by an operator to unroll the film rolls in a concurrent and controllable manner so as to wrap stretch films of the film rolls around the load.

A wagon (90b) includes a plurality of horizontal support bars (91f). A separator roll (12b) is stocked while the horizontal support bar is inserted into a core of the separator roll (12b) around which core a separator is rolled. This can prevent deformation and roll misalignment of the stocked separator roll.

Provided is a film attachment apparatus and a film transport method by which it is easy to switch a film each time, and a film attachment apparatus including the film transport apparatus. The film transport apparatus includes: a film holding unit configured to hold a long-length film; and a film cutting unit configured to cut out the film, in which the film holding unit holds the plurality of films, and the film transport apparatus further includes: a temporary holding unit configured to include a plurality of temporary holding mechanisms that temporally hold the films between the film holding unit and the film cutting unit; and a first transport arm configured to select and pull out one film from the plurality of films which are held in the temporary holding unit.

An apparatus and method for assembling, dispensing and using a laminated paper web transfer tape, an embodiment of the apparatus having a pair of transfer tape spools enclosed within a housing, one transfer tape spool containing a first tape component of the laminated transfer tape and the other transfer tape spool containing a second tape component of the laminated transfer tape, the first tape component being the combination of a substrate having adhesive on both sides and a release liner, the second tape component being a cover flap member having a release coating over at least a majority of one side. The components are unwound from the spools and pressed together such that they become joined along a longitudinal edge strip, then dispensed from the housing. The cover flap member covers one of the adhesive sides of the transfer tape substrate until the moment just prior to transfer of a continuous paper web from a full web spool to an empty web spool, the cover flap member being opened to expose the adhesive by air pressure or resistance.

Implementations of a material roll dispenser for holding and dispensing rolls of materials are provided. In some implementations, the material roll dispenser comprises one or more configurations of a roll dispensing assembly, a platform assembly, a handle assembly, and a wheel assembly each configured to telescopingly position and secure onto a vertical member to form the material roll dispenser.

In some implementations, a method of using the material roll dispenser comprises telescopingly positioning and securing the roll dispensing assembly, the platform assembly, the handle assembly, and the wheel assembly onto the vertical member to form the material roll dispenser. In some implementations, the method of using the material roll dispenser further comprises loading, holding, and dispensing one or more rolls of material from the material roll dispenser.
