(b) A roll in which the tension is not even across the width of the roll. A slack floppy area in the web is caused by the material being stretched and permanently elongated in the tighter areas. Rolls of film or laminate where one side of the material coming off the roll is loose or baggy while the opposite edge is tight is said to have a baggy edge.

Sheet Size Matters. Basic size, or basic sheet size, is the size of a paper before it is cut down to common paper sizes like letter or legal size. Before paper is cut, it is weighed and categorized according to its "basis weight", or how much 500 sheets of that paper weighs .
Your roll forming machine specialist Comprehensive knowhow and the latest technologies form an ideal combination. Custom roll forming machines, high quality roll forming systems and innovative roll forming technology: Ever since its foundation in 1949, DREISTERN GmbH Co. KG has been setting new benchmarks in roll forming.
Plate roll manufacturers commonly rate machines according to baseline material yields between 36 to 38,000 psi. When choosing a roll you must refer to your mill delivery certificates, to your proposed supplier or to the Internet to specifically verify the average yields of the plate you need to roll.
The inside diameter (ID) is the longest distance across the inside dimensions of a tube or pipe. Wall Thickness: Wall thickness is the distance between the outside diameter and the inside diameter of the pipe measured in thousandths of an inch. For pipe: Schedule determines wall thickness.

moderately ductile widththickness requirement to 𝜆𝑝, which is typical of the moderately ductile limit for s most member types. The recent more stringent widththickness seismic requirements have severely limited the use of square and rectangular braces in seismic braced frame applications.
Roll Forming. A series of bending operations are done on the sheet metal for roll forming. A roll forming lines is present on which the sheet metal is fed by a series of roll stations. Each station is a roller die present on both sides of the sheet. These rollers can be at different angles of the sheet.
The bloom containing the plug is then passed between the rolls of the plug mill. Rotation of the rolls reduces the wall thickness. The tube is rotated through 90° for each pass through the plug mill to ensure roundness. The tube is then passed through a reeling mill and reducing mill to even out the wall thickness and produce the finished dimensions.
A roll of paper for wrappin g or toilet use so constructed that the points of attachment and severance between the sheets will be alternately out of parallel lines running through the whole body of the sheets, such points of attachment and severance being upon both sides of the central longitudinal line of the web or series of sheets, so that a pull upon the free end of the web will not be transmitted in a direct line .

Laminate thickness is defined by the base of the board to the top of the board. This thickness is measured in millimeters. The confusing part is some laminate boards come with the pad attached.
Although tube segments of different wall thickness can be assembled within the string construction, it is critical that all of the segments have a uniform material yield strength. The change in specified wall thickness, t, between the adjoining CT segments should not exceed the following specified values:
Groove rolling. A distinction must be made between rolls with different grooves (e. g. in blooming mills) and rolls with identical grooves (e. g. in wire mills). In rolls with different grooves, a pass schedule should be calculated indicating the time percentages and the rolling forces in the individual grooves.
Thickness guarantee. SSAB guarantees a maximum thickness variation within one plate and strip as specified in the tables below. The thickness tolerances according to SSAB ́s thickness guarantee are closer than those specified. in EN 10 029 except for ≥ 80 mm, for which the tolerance range is .
