ALstep

Deliberately simple in its interface, but with powerful control algorithms, ALstep's controller enables the operator to enter all labelling parameters electronically via an intuitive six-digit LCD display. This removes the need to manually move label or product sensors, as per lesser machines. It also includes a product sensor 'shift register', allowing positioning to ensure this device does not foul or clutter the application position.

Control functions include:

• Pre-dispensing adjustment (to align variable label length to the end of the peeler bar)
• Adjustment of label dispensing speed in 0.1meter increments
• Labelling delay adjustment in 0.1mm increments (999mm max delay)
• Automatic recovery for missing labels on the web
• Labels applied counter
• End-of-roll alarm and web break alarm
• Output connection to other systems (e.g. to stop the packaging line in case of error)

ALstep can be equipped with an array of ancillary devices to solve specific labelling problems, such as:

• Batch & date code printers, including TIJ and intermittent thermal (ICE, Markem etc)
• Checking device for near end of label reel, with multi-colours alarm beacon*
• Speed matching via encoder*
• Label sensor for transparent material*
• In-line thermal print engine (see ALstep T)*
• Integrated conveyor systems (see ALbelt)

ALstep is also available in a special ultra-low-cost 'E' (Economical) form for label widths up to 100 mm leading edge, at a maximum application speed of 18m/min. This machine includes reduced dimensions unwind and rewind capacities (as well as the overall machine size) and is ideal for simple low-speed applications where cost reduction is crucial.

ALstep E features a smaller stepper motor and simplified fanless control box, allowing digital adjustment of the main labelling parameters (speed, pre-dispensing and label delay). However, it excludes the ability to encode the machine.

It can provide an alarm signal in case of web break and end-of-roll, but is not compatible with any further accessories of the standard ALstep.
