Floating Flange Rolls for Mark-Free Product
Are your customers telling you that your product is inadequate because of roll marks?
Many companies struggle to keep roll marks off of their tube and pipe and are constantly polishing or reconditioning the tooling. This wastes time and money due to scrap, safety, and downtime.
Roll-Kraft has the solution: Floating flange rolls result in mark-free tube and pipe with guaranteed performance.
Normally, roll marks are due to the speed difference from the throat (root) diameter, which is the smallest diameter of the roll and also the drive point. This point on the roll is turning faster than the largest diameter of the roll, which causes roll marks on your tube and pipe products. Marking is not as noticeable on smaller tubing. However, it is very noticeable on pipe.
Here is how floating flange rolls work to eliminate roll marks:
As you can see by the photos, the rolls are designed in several pieces. The center piece is keyed so it is turning at the speed of the mill. The two outside rolls spin freely, enabling them to turn at the speed of the material being formed. Since the material and outside rolls are now spinning at the same speed, roll marks are eliminated.
Roll-Kraft has designed and manufactured floating flange rolls for over 30 years. We understand that each tube and pipe producer has their own set of criteria for what they consider “mark-free”. Once we fully understand your expectations, we offer our 100% performance guarantee. If you are not satisfied with our products or services in any way, you will receive a replacement or a full refund.
