摘要:
A quantity of material contained in a bank between a pair of calendering rolls is determined by digital imaging technology. Manipulation of digital images provided by a camera yields a light-hued image of material in the bank against a dark-hued background. The light-hued image is then divided into control zones associated with discrete regions of the bank fed by separate feed lines. Quantity and distribution of material in the bank can be controlled by adjusting feed rates based on information obtained through the digital images.

A method and charging apparatus for feeding successively individual strips of a deformable material to a calender for calendering under pressure between at least two rotatably driven calender rolls. The strips are produced from a strand of an elongated mass of deformable material provided from an extruder or rolling mill which is then cut into individual strips transported to a roller conveyor which positions them in a common plane successively at a selected or determined position extending transversely of the roller conveyor rollers in a direction parallel to the length direction of the calender rolls. An intermittently actuated pivotable belt conveyor having laterally spaced endless belts disposed below the roller conveyor and each aligned in a plane with a respective space between next-adjacent rollers of the roller conveyor lifts the individual strips off the roller conveyor to a higher level and advances the individual strips along a planar feed path at fight angles to the path in which the strips are advanced into position transversely of the roller conveyor and inclined toward the calender rolls and delivers them to the calender individually by discharging them successively off a pivot end of the belt conveyor disposed adjacent the feed nip of the calender. The individual strips are delivered extending uniformly parallel lengthwise with the gap between the calender rolls into which they are drawn for producing uniform calender products. The belt conveyor endless belts have free ends intermittently cyclically lifted above the level of the roller conveyor and lowered synchronously by a lever mechanism actuated by an intermittently energized fluid powered cylinder for cyclically effecting lifting a free end of the endless belts upon a detector detecting that an individual strip is in proper position on the roller conveyor for delivery to the calender along the inclined feed path and restoring the belt conveyor to a lowered position below the level of the roller conveyor when an individual strip has been discharged to feed the calender rolls. In the lowered position the belt conveyor is in readiness for delivery of a next sucessive strip to the calender to be calendered.

Disclosed is a materials handling system, a patterned product, and process of fabricating a patterned product. The materials handling system includes an agitation portion having one or more agitators, the agitators arranged and disposed to mix colored particles into a substantially uniform distribution. A processing portion includes a receiving portion arranged and disposed to receive the substantially uniform distribution of the colored particles to form a product with a predetermined pattern. The predetermined pattern is a long-grained, striated or jaspe-grained color pattern. The process includes fabricating a product having such a predetermined pattern. The predetermined pattern is through-patterned as to include colors and textures distributed uniformly throughout the thickness of the product.

In the process for producing a rubber for manufacturing a tire: a calender forms a ply with a mixture of ingredients of the rubber while a conveyor moves the ply in a first direction, a mass of product other than the rubber is deposited on the ply, and the conveyor displaces the ply in a second direction, such that the mass is arranged between two faces of the ply extending one against the other.
