Wulftec WCA-WAVE Automatic Stretch Wrapper

Dual chain driven for balanced movement & no vibration
Quick and easy adjustment of upper and lower carriage travel
The Maintenance-Free spring-loaded carriage gate equipped with spring loaded rollers ensures optimal contact with the stretch film, year after year, without involving maintenance
Wulftec is the only manufacturer to offer a LIFETIME warranty on its pre-stretch roller blue compound
Preset pre-stretch ratios are available from 50-300%
Since all of our semi-automatic SMART Series stretch wrappers wrap 2 inches from the turntable, you are guaranteeing the product is properly secured to the pallet, resulting in a pallet that is more stable for transport, and therefore less damage
No film threading is required and a Lexan cover eliminates operator's ability to reach rollers when gate is closed
Non-Proprietary parts accessible on a local base

Eliminate Downtime Due to Film Changeover

With our carrousel mounted film carriage system, eliminate the downtime created by film loading. Comes with up to 4 complete NO-THREAD powered pre-stretch film carriages that work alternatively, for continuous-operation film reloading. When the machine processes one roller, it automatically replaces the empty spool with a new roll without missing a beat or requiring operator intervention.

Human-Safe Loading Zone

Operator exposure to moving parts during operation is eliminated with our human-safe film loading zone. The film loading zone is now outside of the wrapping zone and is equipped with its own safety devices which do not interfere with the wrapping process. Therefore, the operator can reload the stretch film roll without stopping the machine operation while being 100% safe. Category 3 safety package included.


With up to 4 carriages on the same system, customers can pre-set wrap patterns to use the different carriages for different needs:

Different film sizes (20", 30", 40")
Different film thickness
Different prestretch levels
Diffferent film colors
Logos, etc.

Safety Package Option

Many customers are now asking that we supply our machines in accordance to OSHA specifications for safety. Although OSHA is not specific on what the requirements are, we have added the following features to this system to provide additional safety.

A typical safety package for a rotary arm unit consists of:

Light Curtains
4 beam Light curtains SICK M4000 and a safety monitoring relay. Includes a dual channel e-stop circuit for category 3 safety protection and a 2 button lanyard with estop.
After the forklift driver places the load in the wrap zone, he must back out of the wrap zone clearing the light curtains, verify that the wrap zone is clear of all personnel, then rearm the safety circuit on the lanyard and start the cycle.
If the light curtain barrier is broken at any time during the cycle the machine will stop and will not be able to restart until the safety relay has been reset.
The pre-stretch motor will not be powered during e-stop or wrap zone entrance.
Film can still be easily pulled out of the carriage by opening the carriage gate.
Electric Dump Valve
Addition of an electric dump valve to purge the pneumatic system (including the cylinders) when an E-stop is pressed or when the machine power is off.
Fencing Safety
Three sided safety fencing around process area. Fencing is heavy duty with safety yellow support posts and black wire mesh sections for improved visibility into the wrap zone.
The overall height of the fencing is 90" from the floor, with a 4" sweep space under the panels.
