The Setting of Bends
The movement or change in shape of bends
LAMINATED BENDING
The Process of Laminated Bending
Selection and preparation of laminae - Glues - Pre-bending
Pressing Laminae to Shape
Male and female forms - Fluid pressure - The continuous strip method - Laminated inserts - Two-plane bends - Laminated tubes and cylinders - Moulding
Glue Setting
The setting of laminated bends - Strip heating - Determination of setting times - Miscellaneous setting methods
The Movement and Distortion of Laminated Bends
The movement of laminated bends - Distortion of bends
Theoretical Considerations
Assessment of bending qualities from compressive and tensile stress-strain relationships - End pressures - Tension and compression tests - Minimum radius - Bending moments - Comparison between theoretical and actual bending values - Comments - Movement of bends
