Method of forming a nailing strip by applying a hot melt liquid plastic
Abstract
Abstract This specification disclosed a method of forming nails into a nailing strip of the type which is used in power operated nailing hammers, in which nailing strips the nails are supported spaced apart from one another by easily a hot liquid or semi-liquid state to both sides of the nails simultaneously and squeezed into the space between them. Covering material may be applied to the exterior of the hot material so as to add strength, and also to avoid accumulations of such material on the apparatus. The specification also discloses apparatus for performing such a method in which the nails are arranged to lie on a movable conveyor which is oriented in a plane angled relative to the horizontal whereby to employ both the horizontal and the vertical component of gravitional force acting on the nails and in which the hot material is extruded directly over and under the nails as they are carried on the conveyor from both sides in a direction slanted towards the direction of movement of the conveyor.
