TOILET PAPER AND KITCHEN TOWELS CONVERTING AND PACKAGING MACHINES
To convert parent rolls of tissue into finished/wrapped toilet rolls you can use:
- a simple converting line with semi-automatic rewinder.
- a huge, fast (100-150.000 rolls/8 hours – and more) and expensive full-automatic converting line which, buying a special device, can also manufacture the real “kitchen towel”.
A small line is basically composed by:
- core winder : to make carton cores
- rewinder : you put the parent roll of tissue and machine unwinds it, makes perforation every 12 cm (adjustable lenght), embosses (optionally) the tissue, rewinds it on the core, cuts and tails the last sheet.
Every time machine stops: worker takes out the rewound log and puts another core in the machine.
- logsaw : what you get from the rewinder is a log as wide as the mother roll. By the logsaw you cut it to the finished roll dimension (approx. 10 cm wide)
- wrapper: to pack together several rolls by plastic, starting from a reel of polyethylene or other thermo-sealable material
- (optional) bundler: to make big plastic sacs with several packets of toilet rolls inside
By this line you will get approximately 30-40.000 toilet rolls per 8-hours shift.
By this line you will not get the real “kitchen towel” because this item is composed by two ply of tissue separately embossed and laminated by glue. While the STOP phase of the start/stop cycle too much glue would be applied on a small portion of tissue, destroying it . This is why laminated towels are usually produced by a full-automatic non-stop rewinder.
(Lately, machinery manufacturers developed some devices to laminate tissue by start-stop process but those units are very expensive : when will you pay the investment since capacity of your start-stop line keeps being so low? )
In these non-stop lines (with automatic rewinder, so) all machines are bigger than in the semi-automatic line as they must work much faster and without any stop in process. In the line there is also a log-accumulator so, whenever you put a new parent roll in the unwinder, the rest of the line will keep working, cutting and packing logs stored in the log-accumulator.
For packing toilet paper rolls and kitchen towels most common automatic packaging machine unwind and cut from a reel a sheet of plastic film (PE or BOP etc.) and they wrap by it the wanted number of rolls.
Some market also asks for toilet paper rolls wrapped into pre-made bags: these wrapping machinery are quite different from other ones.
“Reel to packet” wrappers have a 2-3-4 lines feeding section and they can make many different packet-configurations.
Altough last-generation of toilet paper packaging machines can do all possible packet-configurations (and changeover is possible just pushing a button or a touch-screen panel) we divide machines for “flat packets” (rolls are placed in standing position) from wrapping machines for laying position (rolls get into the wrapper and they become wrapped in the same position they have coming out from the log-saw).
Many models may also pack rolls on two layers: they get the first quantity (layer) of toilet paper rolls, they elevate them, they put the second quantity of rolls under first ones, then they wrap all rolls together.
Very often this kind of wrapper is completed by a suitable handle-applicator.
