Modern Bale Opener

Modern bale pluckers can be mainly classified into two categories

Moving bale type Moving beater type

Moving bale type

The first generation bale opening machines were mostly stationary.

Only the bales were moved either backward or forward or in a circle. The examples of these types of machines are Trutzschler multi-bale plucker, karousel-beater type opener by Rieter, etc.

Moving beater type The second generation machines are of

the travelling type i.e. they move past the bales of the layout and extract material from top to bottom.

Travelling machines have the advantages that more bales can be processed as an overall unit, and thus better long-term blend is achieved. 

It should be noted however that these machines extract material only in batches, i.e. they can process only one, two or maximum three bales simultaneously.

Moving beater type If long term blend is needed to be

achieved, then mixing machines must be included downstream from the bale opener.

These machines are completely electrically controlled and extract material evenly from all bales evenly, independently of varying bale density.

Moving beater type In concept, these machines are most

commonly utilized now a day. Machines similar to uni-floc by Rieter are

developed by various other manufactures viz. Optimix by Hargeth Hollingsworth, B12 by marzoli and blendomat by Trutzschler.

Rieter Unifloc A11

UNIFLOC A-11 OPERATIONAL PRINCIPLE

The A 11 UNI-floc processes cotton from all sources and manmade fibres in staple lengths of up to 65 mm. The bales being opened are placed lengthwise or crosswise on both sides of the bale opener, and the take-off  unit can process up to four different assortments.

Reduction of the raw material into micro-tufts is done by the double teeth on the take-off roller and the grid with closely set clamping rails.

UNIFLOC A-11 OPERATIONAL PRINCIPLE

The unique geometry of the double teeth ensures the uniform  treatment of the entire bale surface.

Retaining rollers travelling with the take-off unit prevent bale layers from sloughing and ensure precise, controlled operation over the entire height of the bale.

The A 11 UNI-floc still produces small tufts, even at maximum output of 1400 kg/h.

UNIFLOC A-11 OPERATIONAL PRINCIPLE

The take-off unit is lowered by a preselected or computed distance at each pass.

The fan incorporated in the swivelling tower extracts  the opened tufts and feeds them into the tuft channel running between the guide rails.

Transport to the following machine is pneumatic.
