  • SHREDDER WITH FEEDING GAP ADJUSTING DEVICE
    Publication number: 20140014753
    Abstract: A shredder includes an adjusting device for adjusting a feeding gap, so that the width of the feeding gap does not exceed a maximum shredding thickness value. The adjusting device is located at a side of the feeding channel. A roller is located at another side of the feeding channel. The feeding gap is formed between the adjusting device and the roller. After the papers in the feeding channel are transferred through the feeding gap, the papers are cut into strips or fine particles by a cutting blade assembly.
