Alpha Modular

Alpha Compact Modular

For certain specific situations, the standard Alpha Compact 120/150 and Alpha Compact 120/150 TB may not be 100% suitable to meet your special application requirements. For these cases, we can build a custom-tailored system, because the Alpha labelers are completely modular.

Different Applications

You can choose from several applicators and configurations to apply labels on any area of the products. You can opt to apply labels on the lids and the top of the products or on the side of boxes or flat-sided bottles. With a rotative tamp, you can also apply on the front or rear of boxes. With Wipe-On and special conveyors, you can also put the labeler below, on a nose-up orientation, to apply labels on the bottom of the products or even to label bottles, flasks, cans and other cylindric or conical products, by wrapping the label around them. If you pick the Wipe-On method, compressed-air will not even be required. The applications usually do not require product stops and products can travel at 50m/min. With a single stand, you can adjust the system to apply on any position and the labeler is available in left- or right-hand versions (LH/RH).

Excellent Precision

Apply your labels in the right spot with millimeter precision. No more misplaced, crooked or wrinkled labels.

Easy to Use

Digital and Analog HMI

This system is very easy to set-up. You just need to calibrate the labeler once to the label size being used. After tuning the positioning, just let it do the job. The system detects missing labels on the roll and advances automatically to the next one, so no product will pass unlabeled. You can perform the calibration and adjust the speed easily using the digital or analog HMI. The digital version allows advanced configurations and notifications, but with the analog version you can do very quick and precise adjustments.

Few Stops


With an unwinder that allows big label rolls and a rewinder for the label liner that works in 1:1, that is, with capacity to rewind the complete roll, you will have to make few stops to do label roll replacements.

Industrial Motor

The labeler is moved by a powerful stepper motor that allows precise feeding speeds, eliminating wrinkles during the application.

Label Counter

When using the digital HMI, you will have a label counter so that you know how many application cycles were performed. The counter has a capacity for 10 000 applications and then starts over automatically. You can reset the counter at any moment or you can use a countdown feature by setting the counter to a value greater than zero. In that case, the labeler will automatically stop the labeling process when the counter reaches zero.

Various Peeler Bars Available

Alpha Compact Pressure Units

There are several peeler bars available so that the labeler can be adapted to any kind of application. You can choose to use a pressure roll for flat products or a pressure brush for irregular products. There is even a pneumatic peeler bar that moves using compressed-air and enables the application on products whose heights vary slightly.

Print the Lot and Expiration Date

Alpha Compact with X1JET

You do not need a complex print-and-apply system if all you want is to add small texts like the lot and expiration date to your pre-printed labels. You can equip your Alpha with our compact inkjet system X1JET HP or X1JET LX, which only requires installing a mounting bracket and connecting a cable.

High Quality Sturdy System

These labelers are very robust and reliable, with a lifespan that goes over 15 years. Built exclusively with quality materials, you will not find a single speck of rust and, besides the occasional cleaning of possible label adhesive build-up, they do not require neither lubrication or maintenance.

Operational Redundancy

For the most demanding applications, we have an optional controller for Zero Down Time into which you can connect two Alpha Compact systems. Only one system is labeling, but if the labels run out or an error occurs, the controller automatically switches the labeling operation to the other system. Thus, you can replace the label rolls without needing to stop the production line and no product passes through unlabeled.

Safe and Certified Systems

These systems have CE certification and follow all European safety norms. Most of the standard system are complete complying systems (CC) with the safety norms and do not require additional protections or safeguards, given the fact that they do not exert forces over 50N. When the application rate is critical, there are faster versions in which the system is unlocked to go beyond the 50N of force threshold, being these versions identified as NC (not completed), since they require additional safeguards. If you choose a NC version, the system will include door-open sensors that will immediately halt the labeling operation when the safeguards are opened, so that the system cannot cause injuries. Furthermore, they also bring emergency kill switches to immediately stop the system manually.

Quiet and Energy Efficient

A system that applies labels like a machine-gun must consume a lot of power and be very loud... Or not! This system consumes as much power as a computer and without fans it is relatively quiet, keeping the noise emission below 75dB(A).

Easy Integration

The system can receive remote signals to trigger the application. The input signals work in active and passive modes, that is, the 24V can be sent by the PLC or supplied by the labeler itself. Like this, only a contact needs to be switched. As for the output signals, the labeler informs if it is in normal or in error conditions, if the label roll is near the end and can also send a synchronization signal that can be configured to be active during or after the application cycle, in the last scenario, allowing a definition of a delay and duration in which the signal will be active.

Approved by System Integrators

With the Weber® policy for Global Export, the system integrator companies can export our labeling systems as part of a bigger system and the final user gets all the technical support in the destination country, performed by the local distributor of that said country, all completely transparent and without additional costs. All that a system integrator must do is mention that the system is for resale and when the destination country is known, inform us about it so that we can proceed with the transfer of responsibility of the system to the local distributor.

100% Modular

Because these systems are modular, multiple combinations are possible. Equip your Alpha with unwinders tailored to your needs for greater flexibility when the available space is limited and pick the application method by installing a linear tamp applicator, a swing-tamp or the simpler peeler bars for Wipe-On. Create a fully customized system to meet your application requirements. The chosen configuration is previously tested so that the system is perfectly tuned.
