Abstract: A sewing machine presser foot lubrication system which includes apparatus to directly supply a lubricating fluid to the underside of a presser foot. The apparatus includes a small lubricant flow tube attached to a forwardmost underside portion of the presser foot. By such direct attachment of the lubricant flow line to the presser foot, a more effective lubricating function between the presser foot and a work piece is achieved. The apparatus further consists of a lubricant reservoir and the appropriate valving to control the lubricant flow rate therefrom. The flow tube is in two sections wherein a flexible second portion can be quickly disconnected from a rigid first portion which is integral with the presser foot.

Abstract: A padded book panel which utilizes three flat chipboard layers between which are positioned an upper undulating layer and a lower undulating layer.The undulating layers are of generally longer fiber length than the flat chipboard layers.In a preferred embodiment, the upper undulating layer has longer arms or flutes thereon so that, when passed through a treating pressure roller, the arms of the upper undulating layer are permanently bent or creased. The arms of the lower undulating layer, being of shorter height, are not bent during the roller treating softening process.The resulting structure is then utilized as an economically manufactured and high-quality padded book panel.
