Do you die cut labels? If so, you know the challenges associated with rewinding matrix. Matrix is typically waste material, left behind after the label shape is die cut from the base stock. Most of the time this matrix is stripped off a release liner backing and wound onto a cardboard core mounted on a rewind shaft. Many challenges arise when winding this matrix. Tension control may be very difficult because matrix is typically kept to a minimum to decrease costs associated with waste material. Matrix breaks and roll deformation are common and can result in machine stoppage. If recycling of the matrix is desired, the cardboard core may be viewed as an unacceptable contaminant to the recycling process. Besides stopping the machine to change unwind and rewind product rolls, extra stops may be necessary to remove fully rewound matrix rolls.
To combat these matrix winding challenges, it may be wise to consider a pneumatic matrix removal system. These systems can be designed to handle matrix with and without exposed adhesives. Pneumatic conveying systems utilize a blower and venturi combination to generate a powerful material conveying air stream. Matrix is fed into the system and conveyed, pneumatically, to a waste collection method. Some advantages to utilizing this technology include:
Use of a pneumatic matrix removal system will eliminate the headaches associated with winding waste matrix. More importantly, it will prove fast ROI.
