A.CELLI NONWOVENS
A.Celli Nonwovens is a world leader in the design and manufacture of winders, slitter-rewinders and unwinders. The company’s new area of interest is roll handling and packaging technology, where it offers new technology known as Slittopack, which integrates winding, slitting and packaging into a synergistic operational concept for nonwovens plants. Specially developed to be integrated with mainstream technologies such as Corematic core positioning and Slittomatic knife positioning systems, Slittopack’s main features are:
• Modular design to fit different layouts
• Flexible technology to fit different budgets
• Value-adding concept (high throughput production lines)
• Fully interfaced with upstream line
• Single user interface
• Order pulled operation
• Reduced manpower
ACCUSENTRY
AccuSentry is introducing line scan technology for the inspection of products such as diapers, incontinence items, pants, panty liners and hygienic pads. Unlike the area scan camera, which captures the complete image of the product to be inspected, the line scan camera captures one very small slice of the product at a time and builds it into a complete product image. The advantage of the line scan camera is the ability to capture the image of the product through a very narrow viewing slot. This approach greatly limits the space requirement of the camera system. As high speed production lines are getting more compact, the space between the last component placement and the final packaging is getting more limited. The line scan camera provides the ability to inspect the product through a few millimeters of product viewing space. In addition, because the light is hitting all the small slices of the product at the same angle, the lighting uniformity of the product is greatly enhanced. This results in much more consistent inspection. The line scan camera also has the ability to provide very high resolution image. For example using a 2k line scan camera, the system delivers very detailed inspection through an image with 16 mega pixel size resolution.
ACRISON INTERNATIONAL
SAP feeding specialist Acrison’s new flow splitter (shown here), is designed for separating SAP streams into smaller streams in the production of multi-layer absorbent hygiene products. Crucially, the splitter maintains the required split ratio even as the SAP rate is increased or decreased. It does this by incorporating technology from Acrison’s patented AirSAP device, which was developed to ensure a consistent spread of SAP across a desired width, for instance, in the production of sanitary napkins with an absorbent core using an airlaid web supplemented by a layer of SAP for extra absorbency.
“We realized that some manufacturers were attempting to produce a multi-layer product by taking a single SAP feeder and then dividing the output stream into two separate streams,” explained Acrison segment manager, John Wheeldon. “Often, they were doing this using fairly crude splitter devices that could be adjusted to provide the necessary split ratio at a fixed rate, but they noticed that the split ratio varied wildly as the rate was increased or decreased. This caused particular problems at line ramp-up or during periods of low speed running e.g. during roll splicing. We realized there was nothing on the market to meet this requirement so we adapted our patented AirSap technology to produce a splitter which was able to maintain a consistent split ratio. The reaction of the market tells us the development of such a device was long overdue.”
