A hand held combined tool for drywall taping including a drywall tape applicator attached to a smoothening blade is described. The dry wall tape applicator includes a gated protrusion for feeding a dry wall tape through a ridged slot and to be held securely in position by a user before dipping the dry wall tape in a joint compound container to coat the dry wall tape with the joint compound on both side of the dry wall tape. The user then pulls the dry wall tape through the gated protrusion and the ridged slot to obtain a uniformly dual side coated drywall tape ready to be placed on a joint and to be immediately smoothened with the smoothening blade attached to the dry wall tape applicator.

An automated drywalling system for applying joint compound or plaster to drywall pieces. The system includes a robotic arm and a mudding end effector coupled at a distal end of the robotic arm, the mudding end effector configured to apply joint compound or plaster to a target surface. The system can further include a computing device executing a computational planner that: generates instructions for driving the mudding end effector and robotic arm to perform at least one mudding task that includes applying joint compound or plaster, via the mudding the end effector, to one or more joints between a plurality of drywall pieces, the generating based at least in part on obtained target surface data; and drives the end effector and robotic arm to perform the at least one mudding task.

The circular perforated drywall tape comprises a joint tape, a pipe, and a drywall panel. The drywall panel further comprises a pipe aperture. The pipe passes through the pipe aperture. The circular perforated drywall tape seals the joint between the drywall panel and the pipe. The circular perforated drywall tape is perforated such that a removable knock out sizes the joint tape to match the size of the joint between the drywall panel and the pipe.

The present invention relates to an improved drywall tape for use in drywall installation applications. More specifically, the improved drywall tape is comprised of a woven mesh body portion positioned between, and fixedly attached to, two solid end portions. The shape and size of the mesh body portion is meant to substantially fill the valley created by two factory tapered edge portions of adjacently hung drywall sheets, thereby requiring less joint compound/drywall mud than would otherwise be required to finish the drywall joint and reducing labor/material costs. The shape and configuration of the improved drywall tape also enables the same to be used to finish an inside corner, and may further comprise an adhesive backing for easier installation.

An automated sanding system that includes a robotic arm and a sanding end effector coupled at the distal end of the robotic arm, with the sanding end effector configured to sand a target surface. The system can further include a computing device executing a computational planner that generates instructions for driving the sanding end effector and robotic arm to perform at least one sanding task that at least includes the sanding end effector sanding a target surface, the generating based at least in part on obtained target surface data; and drives the end effector and robotic arm to perform the at least one sanding task.

A tool assembly includes a handle and a connection end which is connected to the handle by way of blow molding or ultra-sonic fusion. The connection end can be made by plastic injection molding. The handle can be made by way of blow molding. The connection end has a slot defined axially therein. A blade includes a body and a toothed portion. The toothed portion of the blade is connected to the slot of the connection end. The toothed portion is inserted into the slot of the connection end when the connection end is molded by way of blow molding so that the toothed portion of the blade is connected to the slot of the connection end. The toothed portion has multiple teeth and each tooth includes an inclined edge tapered toward the downward toward the connection end.

An automated drywalling system network that include one or more automated drywalling systems that each comprise a robotic arm. The automated drywalling system network can also include one or more drywalling end effectors configured to couple to a distal end of the robotic arms of the one or more automated drywalling systems. The drywalling end effectors can include a drywall hanging end effector; a drywall mudding end effector; a drywalling sanding end effector; and a drywall painting end effector.

A caulking assisting device has of a fixed frame mounted to a filler coating-supplying device, a rolling part mounted to the fixed frame, a movable frame and an elastic element. The positioning frame has a pair of first limiting recesses and a pair of second limiting recesses. The movable frame is pivoted to the fixed frame and is rotatable, and a tapered roller is pivoted at the end of the movable frame. Meanwhile, the elastic element is disposed on the movable frame, while a positioning protrusion is located at both ends respectively. As a result, the tapered roller can be moved to a use position and a non-use position by the rotation of the movable frame, thereby switching between the rolling part and the tapered roller while in use.

A taping tool is provided, the taping tool includes a housing, a spool disposed at one end of the housing, and a blade disposed at another end of the housing. The blade has a first end defining a first cutting tool and a second end defining a second cutting tool. The blade is retained by the housing in either a first configuration in which the first cutting tool projects from the housing or in a second configuration in which the second cutting tool projects from the housing.

A utility knife is provided for supporting a blade in use, the blade defining a cutting edge, the utility knife including a handle portion, a blade holder positioned proximate the handle and defining a longitudinal axis, the blade holder configured for retaining a blade, and a fastener for selectively retaining the blade within the blade holder in a plurality of orientations. In a first orientation the cutting edge extends substantially parallel to the longitudinal axis of the blade holder, and in a second orientation the cutting edge of the blade extends transverse to the longitudinal axis of the blade holder.
