Systems and methods for automated repair and maintenance operations on a railroad track comprise a work head that is automatically moved over the railroad track according to a predetermined pattern, such as the movement of an applicator for tie plugging compound according to a predetermined pattern of spike holes. The automated repair and maintenance operations may be coupled to systems and methods for automatically detecting a feature on a railroad track that comprise two or more distance measurement sensors that travel over the railroad track. Features on the railroad track are detected where the distance measured by each sensor falls within two different predetermined distance ranges.

The invention relates to a device for applying a hot-melt to a web of material. The device includes a driven roller and a nozzle with a nozzle channel arranged adjacent the driven roller for supplying a hot melt through the nozzle channel to the surface of the roller. The invention also relates to a combination of a device according to the invention and a web of material, which web of material is guided along the driven roller and wherein the nozzle channel exits in front of the nip of the web of material and the driven roller.

A paint applicator apparatus for applying a paint line to a moving strand of a tire component comprising a paint neck and a paint head. The paint neck includes a receiving neck portion, a discharge neck portion, and a paint supply passage. The receiving neck portion extends along a receiving neck portion axis and the discharge neck portion neck portion extends along a discharge neck portion axis. The paint supply passage includes a paint inlet in the receiving neck portion and a paint outlet in the discharge neck portion. The receiving neck portion axis and the discharge neck portion axis define an obtuse angle. The discharge neck portion axis is oriented substantially parallel to the moving strand, and the receiving neck portion axis is oriented upwardly relative to the moving strand. The paint head is coupled to the discharge neck portion and includes a rotatable paint wheel for carrying paint from the paint outlet to the moving strand.

A layered object manufacturing system is described. The system in one arrangement provides for the use of water based adhesives to bind successive layers of paper in generation of a three dimensional model. The paper can be provided in conventional paper sizes and is moveable within the system from a storage stack to a build object location, individual pages at a time. The system typically effects the application of adhesive onto the paper using an adhesive applicator wheel having a plurality of circumferentially spaced apart recesses for receiving adhesive. The wheel is rotatable to convey adhesive filled in one or more recesses to a targetsubstrate and to deposit controlled amounts of adhesive at discrete points thereon.

A brush (400) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (400) comprises a body (402) having a rotational axis (438). The body (402) comprises a first end (407), a second end (411), opposite the first end (407), and a channel (408), comprising an axial inlet (409) and an outlet (480). The axial inlet (409) is at the first end (407) of the body (402) and is coaxial with the rotational axis (438). The brush (400) also comprises bristles (420), extending from the body (402) so that the bristles (420) are not parallel to the rotational axis (438) of the body (402).

A brush (200) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (200) comprises a body (202), having a rotational axis (238) and comprising a first channel (208) that comprises an inlet (209) and a first outlet (280). The inlet (209) is coaxial with the rotational axis (238) and the first outlet (280) is offset from the rotational axis (238). The brush (200) also comprises tufts (222), extending from the body (202) and each comprising at least one bristle (220) and a tip (227). The brush (200) further comprises a first tube (210), communicatively coupled with the first outlet (280) of the first channel (208) of the body (202).

A coating device for the register-accurate application of plastic material to a carrier sheet comprises a first coating roll and a downstream second coating roll, wherein each of the first and second coating rolls has at least one cavity that can be filled with plastic material by means of at least one nozzle. First and second stripping means strip the respective first and second coating rolls. The first coating roll interacts with a first mating roll and coats a first carrier sheet side and the second coating roll interacts with a second mating roll and coats a second carrier sheet side. The second mating roll comprises at least one mating cavity corresponding to the at least one first cavity. In addition, the coating device comprises at least one carrier sheet positioning device and a coated region detection device. Related methods of coating a carrier sheet are also disclosed.

A girth weld coating machine has an application head rotatable about a pipeline. A reservoir of coating material is carried on the application head and progressively dispenses coating material on to the girth weld. The coating material is applied to the pipe surface by a roller to spread and distribute the coating over the surface.
