Abstract
An assembly and method for rotating and placing a strip of material on a substrate making use of a conveyor which includes a contour-changing conveyance surface on which a strip of material is conveyed and a rotatable transfer element. The rotatable transfer element has a contoured strip securing surface. At a point of interaction of the transfer element and the conveyor, the conveyance surface assumes a contour corresponding to that of the strip securing surface. The transfer element then secures the material strip from the conveyor, then rotates the strip of material to a selected degree of angular rotation and then deposits the rotated strip of material in surface contact with an adjacent moving surface.
Claims27
An assembly comprising:
- a conveyor including at least one contour-changing conveyance surface on which a strip of material is conveyed and at least one transfer element having a strip securing surface with a curved planar contour effective at a point of interaction with the conveyor to secure the strip of material from the at least one contour-changing conveyance surface, then rotate the strip of material to a selected degree of angular rotation and then deposit the rotated strip of material in surface contact with an adjacent moving surface,
- wherein at the point of interaction of the at least one transfer element with the conveyor the at least one contour-changing conveyance surface assumes a contour corresponding to the curved planar contour of the strip securing surface.
In an assembly comprising a conveyor having a conveyance surface on which a strip of material is conveyed and at least one rotating puck member effective at a point of interaction with the conveyor to receive the strip of material therefrom and then rotate the strip of material to a selected degree of angular rotation and then place the rotated strip of material in surface contact with a moving surface, the improvement comprising:
- the at least one rotating puck member having a convex contoured strip securing surface and the conveyance surface at the point of interaction with the at least one rotating puck member assuming a concave contour corresponding to the convex contour of the strip securing surface of the at least one rotating puck member.
A method for rotating a strip of material and placing the rotated strip of material in surface contact with a moving surface comprising:
- providing at least one strip of material having a first axis in a first angular orientation on a first continuously moving contour-changing conveyance surface,
- securing the at least one strip of material from the first continuously moving contour-changing conveyance surface onto a rotatable transfer element having a strip securing surface with a curved planar contour, at a conveyance point whereat the conveyance surface has a contour corresponding to the curved planar contour of the strip securing surface,
- rotating the at least one strip of material secured to the rotatable transfer element a selected degree of angular rotation so that the first axis of the at least one strip of material is in a selected second angular orientation and
- positioning the rotated at least one strip of material strip in surface contact with a moving surface.
