RT7700-B - Battery-powered automatic adhesive dispenser

RT7700-B Battery-Powered Automatic Adhesive Dispenser

The RT7700-B is a automatic, battery-powered, industrially programmable tape dispenser, designed for the precise and repeated dispensing of adhesive tapes at workstations where mobility is essential.

It is particularly suited to professionals who regularly handle technical adhesive tapes, very sticky adhesives, textile tapes or double-sided tapes, while needing a compact, portable and self-contained machine.

Programmable and automated cutting

The RT7700-B allows you to program the cutting length between 5 and 999 mm. It can store up to 6 different programs, identified by letters, to facilitate the chaining of several tape formats on the same workstation.

The distribution can be used:

• in semi-automatic mode

• in automatic mode

• in programmed sequential mode

This flexibility in adjustment makes it an ideal solution for repetitive production operations as well as for more variable cuts.

Mobility and autonomy in the field

The major difference between the RT7700-B and the wired version lies in its battery power supply.

This autonomy allows:

• to work without a nearby electrical outlet

• to easily move the machine from one station to another

• to use the reel on temporary, mobile or remote workstations

• to eliminate cables on the floor and installation constraints

The RT7700-B is therefore perfectly suited to workshops, logistics areas, mobile packaging stations and flexible industrial environments.

Compatible with many ribbons

The RT7700-B accepts a wide variety of materials:

• single-sided adhesive tapes

• double-sided ribbons

• textile ribbons

• technical ribbons

• protective films

• technical papers and flexible materials

It accepts reels from 6 to 60 mm wide, up to 300 mm outside diameter, with all types of mandrels thanks to its hubless system.

Programmable memory for up to 6 lengths

The RT7700-B allows you to save up to 6 cut lengths to facilitate format changes and automate repetitive sequences.

Automatic or semi-automatic distribution methods

Depending on the operator's needs, the machine can operate:

• with manual trigger

• available for automatic distribution after collection

• in a programmed sequence

Using two reels simultaneously

The RT7700-B can accommodate two reels at the same time thanks to an adjustable separator.

This configuration allows:

• the work of two operators

• a time saving on production workstations

Secure cutting system

The machine is equipped with a protected cutting system suitable for professional use in an industrial environment.

Compact and portable design

Thanks to its small size and light weight, the RT7700-B is easy to move and integrate into crowded or mobile workstations.

Programmable cutting to precise length

The RT7700B is primarily a automatic industrial tape dispenser with programmable cutting, powered by a battery. The cutting length is easily adjusted using the "+" and "-" buttons located on the control panel.

The user can define lengths between 5 and 999 mm, with a maximum tolerance of ± 1 mm, guaranteeing a custom, precise and perfectly repeatable cut, essential for demanding industrial productions, including on mobile or temporary workstations.

Automated or semi-automated distribution

This automatic battery-powered industrial tape dispenser offers two operating modes, allowing it to adapt to all production rates:

Semi-automatic mode

After each cut, the operator triggers the next distribution by pressing the START button. This mode offers an excellent compromise between manual control and speed of execution.

Automatic mode

Thanks to a photoelectric detection cell, the RT7700B automatically dispenses a new piece of tape as soon as the previous one is retrieved. This mode greatly reduces manual handling, improves operator comfort, and significantly increases productivity, even without mains power.

Programmable memory for up to 6 lengths

The RT7700B retains the advanced programming system of the RT range. It allows saving up to 6 different cutting lengths, identified by the letters A to F.

Each program can correspond to a specific length (e.g. A = 10 mm, B = 20 mm, C = 30 mm, etc.), an ideal feature for operators handling several adhesive formats successively, at the same station or while moving.

Intelligent navigation between programs

Two navigation modes are available:

• Manual selection: switching between programs using the selection key

• Sequential Automatic Selection: The user defines the number of pieces to be dispensed for each program; the dispenser then automatically alternates between programs A, B, C, etc., without human intervention.

This feature enables advanced automation of cutting sequences, even in a mobile environment.

High performance and cadence

The RT7700B guarantees a high and consistent output speed while ensuring consistent cutting quality. This performance reduces downtime, optimizes throughput, and minimizes tape waste, even during intensive battery operation.

Great versatility of the reels

Like the RT7700, the RT7700B does not have a hub, which allows it to accommodate:

• Ribbon width: from 6 to 60 mm

• Outer diameter of coil: up to 300 mm

• All chuck diameters

An adjustable holding system ensures perfect stability of the tape, regardless of the dimensions of the reel.

Simultaneous use of two reels

The RT7700B can operate with two adhesive rolls simultaneously thanks to an adjustable separator clipped under the base of the device.

This configuration allows:

• The use of two different ribbons (width, color or type)

• The simultaneous work of two operators

• Saving time and space on production workstations

In dual-track configuration, the detection cell activates only when both tapes have been retrieved, ensuring synchronized and secure distribution.
