A roller tool for use in plasterboard finishing is disclosed. The tool has a first wing and a second wing, and an edge portion of the first wing is pivotably connected to an edge portion of the second wing. The tool also has one or more first wing rollers connected to, and able to pivot/roll relative to, the first wing, and one or more second wing rollers connected to, and able to pivot/roll relative to, the second wing. In use, the tool can be pressed against surfaces on respective sides of a joint or line between adjacent plasterboard panels, such that the first wing roller(s) contact with the surface on one side of the joint or line and the second wing roller(s) contact with the surface on the other side of the joint or line. When the tool is thus pressed against the surfaces on respective sides of the joint or line between adjacent plasterboard panels, the first wing and the second wing are caused to align (by pivoting relative to one another, if necessary) with the plasterboard panels on the respective sides of the joint or line, such that the first wing roller(s) become(s) correctly oriented relative to the plasterboard panels on one side of the joint or line, and the second wing roller(s) become(s) correctly oriented relative to the plasterboard panel(s) on the other side of the joint or line.

A three-dimensional (3D) drawing pen can include a housing that has a port that permits insertion of a strand of material into the housing, an actuator for controlling a movement of the strand, and a nozzle assembly configured to permit the strand to be extruded out of the 3D drawing pen in a form that retains its shape against gravity in free space to draw a 3D object.

A utility tool with at least one blade that is capable of being disposed at least partially within the body of the utility tool. The at least one blade may swivel around an access of rotation and engage with a locking mechanism to keep the blade secure when in use and secure in the body when in a closed position.

Disclosed is a corner bead for mounting on an internal or external corner of a building construction, the corner bead including a first flange and a second flange which are configured with a longitudinal extension and a generally L-shaped cross-section. Furthermore, the first flange has a first surface intended for facing the building construction and the second flange has a second surface also intended for facing the building construction, wherein at least one of the first surface and the second surface is at least partially coated with an adhesive element. Also disclosed is a method for manufacturing an absorbent article of the above-mentioned type.

A caulking alignment device including a base substrate having at least two panels, an alignment tab located on each panel with each alignment tab having a front side and a back side with the front side of the alignment tab removably attached to the corresponding panel by a non-permanent adhesive with each of the tabs supported on the base substrate in a spaced and perpendicular condition from each other, a non-permanent adhesive located on each of the back sides, a removable film covering the adhesive on each of the back sides, and caulk receiving channels formed from a spacing between the alignment tabs.

A drywall mud applicator tool includes a body having a wall engaging applicator face, a first end, a second end, a first side and a second side. A first wheel is mounted for rotation on an axle which is secured to the first side adjacent to the first end. A second wheel is mounted for rotation on an axle which is secured to the second side adjacent to the first end. A third wheel is mounted for rotation on an axle which is secured to the first side adjacent to the second end. A fourth wheel is mounted for rotation on an axle which is secured to the second side adjacent to the second end. A first mud containment skirt extends along the first side from the first end to the second end. A second mud containment skirt extends along the second side from the first end to the second end.

An automated drywalling system network that including one or more automated drywalling systems that each has a robotic arm. The automated drywalling system network can also include a computational planner that generates instructions for the one or more automated drywalling systems to perform two or more drywalling tasks associated with a target wall assembly. The two or more drywalling tasks can include a hanging task that includes hanging pieces of drywall on studs of the target wall assembly; a mudding task that includes applying joint compound to pieces of drywall hung on studs of the target wall assembly; a sanding task that includes sanding joint compound applied to the pieces of drywall hung on studs of the target wall assembly; and a painting task that includes painting sanded the joint compound applied to the pieces of drywall hung on studs of the target wall assembly.
