In a method of forming a pattern of granules on a moving asphalt coated sheet, a blend drop of first and second granules is discharged onto the sheet. The blend drop forms a granule deposit on the sheet including an inner portion of first granules and an outer portion of second granules. An apparatus for use in the method includes a nozzle having an orifice for discharging a blend drop of first and second granules onto the sheet. A first granule feed chamber is provided for feeding first granules into the nozzle. A second granule feed chamber is provided for feeding second granules into the nozzle. The first and second granule feed chambers are positioned so that the first granules are fed inside the second granules in the nozzle.

In a method of forming a pattern of granules on an asphalt coated sheet moving in a machine direction, a flow of separate first granules and second granules is discharged onto the sheet. The flow of granules is rotated to form a pattern of first and second granules on the sheet that changes along the machine direction. Another embodiment of the invention provides a method of forming a pattern of granules, in which the flow of granules is oscillated in a direction transverse to the machine direction. The flow of granules can also be discharged intermittently onto the sheet.

Method of rotating or oscillating a flow of granules to form a pattern

In a method of forming an irregular pattern of granules on an asphalt coated sheet, a flow of granules is discharged toward the sheet. The granules are deflected onto the sheet with a deflector having an irregular surface to form a granule deposit having an irregular pattern. In one embodiment of the method, the deflected granules are controlled with a shield. Apparatus for forming an irregular pattern of granules on an asphalt coated sheet includes a granule applicator for discharging a flow of granules, a deflector having an irregular surface for deflecting the granules, and optionally a shield for controlling the granules.

A multiple section door system, such as an overhead residential garage door, wherein a variety of different door front configurations are formed with a limited number of panel designs by flipping or turning at least one panel relative to an adjacent panel. Each panel includes identical structured joint members along two longitudinal edges thereof which enable one panel to be 'flipped' or turned such that the lower edge becomes the upper edge and vice versa, while an adjacent panel may remain in its original orientation. A third structured joint member is connected between the two adjacent joint members of adjacent panels. The third structured joint member is a male member, while the two structured joint members attached to each panel are female members. Adjacent female joint members of two panels form a universal pinch resistant joint with the male joint member.
