A one-handed tool for use in application of seam tape or seaming tape. The device has a frame with an upper support with an ergonomic grip, with a finger guard or shield extending across the front of the grip to protect the user's fingers. A primary roller support and a secondary roller support extend downward from upper support. Each roller support comprises a pair of parallel arms extending downward at angles behind and in front of the upper support when in use, supporting a primary roller and a secondary roller, respectively. The primary roller is used to apply pressure to the seaming tape, while the secondary roller is used for stability and to apply additional pressure to the edges of the seaming tape. A retractable blade or knife may be located on one or more roller supports.

A core insert (103) for insertion into a core (700) of a roll (500, 600) of material and a hand tool using the core insert for applying the material to a surface (1100). The insert (103) includes a gripper sleeve bearing (7) rotatably connected to a spindle hub (101) attached to an axle shaft (1). The bearing (7) has tapered axial splines (104) extending away from center of the bearing (7) configured to grip the inner surface of the core (700). The hand tool includes the core insert (103) and an axle shaft (1), a handle shaft (2) and a shaft connector (9). The axle shaft (1) is insertable into the core (700) with the bearing (7) inserted into the (700) core to releasably and frictionally engage the core (700) so that the roll (500, 600) is rotatable about the axle shaft (1) along with the bearing (7).

The present invention provides a dispenser of stretch wrap, comprising a main body with a first end, a second end, a first connector portion proximate to the first end, a second connector portion proximate to the second end, a first braking mechanism at the first connector portion, a second braking mechanism at the second connector portion, a tension controller terminating an end of the second connector portion, the first connector portion and second connector portion are adapted to engage two ends of an elongated core with stretch wrap film, the tension controller comprising an adjustable portion that is rotatable and in mechanical communication with a movable part located intermediate the tension controller and the second connector portion and the adjustable portion is a rotatable knob, and the movable part is a clutching mechanism connected to a shaft; characterized in that the tension controller further comprises a tension limiting mechanism.

A coiler bar assembly includes a coupler housing and a bearing housing used to suspend a reel shaft above a surface. The reel shaft is configured to include bearings to permit its rotation relative to the housings. The coupler housing includes a receiving plate coupled to an end of the reel shaft and a coupler that is engaged with a motor shaft. The motor shaft extends up to the receiving plate. A handle is included and is pivotally coupled to the coupler housing and the coupler about two separate axes. Pivoting the handle permits translation of the coupler along the motor shaft to selectively engage the receiving plate. When engaged, rotation of the motor shaft induces rotation of the reel shaft. The handle is operated externally from the coupler housing.

A dispenser includes a rotating member defining a first end and a second end, the rotating member defining an outer surface, the rotating member defining an axis of rotation, the axis of rotation extending from the first end to the second end; a holding member defining an inner surface, the inner surface enclosing an engaging portion of the rotating member, the holding member configured to rotate relative to the rotating member, the inner surface defining a protuberance extending radially inward with respect to the axis of rotation towards the outer surface; and a cap attached to the first end of the rotating member.

A stretch film dispenser with a tension adjustment device includes a frame. The frame is provided with a film dispensing unit and the tension adjustment device. The tension adjustment device includes an adjustment rod. One end of the adjustment rod is threadedly connected with an adjustment unit. An elastic unit is connected between the frame and the film dispensing unit. When the adjustment unit rotates along the adjustment rod to generate downward axial displacement, the adjustment unit pushes the frame and the elastic unit to press the film dispensing unit, so that the film dispensing unit can be quickly adjusted in a different tension state when the film of the film roll is stretched.

A stretch film dispenser with a moving device includes a frame. The frame includes a bottom seat and a coupling seat. A tubular member is connected between the bottom seat and the coupling seat. The tubular member is provided with a telescopic rod. The bottom seat is provided with a moving unit. A bottom surface of the moving unit is provided with at least two first moving members. When in use, the telescopic rod is pulled to a height suitable for holding, and then the user holds the telescopic rod to pull the stretch film dispenser. The stretch film dispenser can be moved through the moving unit, thereby achieving the effect of moving the stretch film dispenser easily and conveniently.

A stretch film dispenser with a lifting device is disclosed. The lifting device includes a first operating unit. The first operating unit has a first through hole. The first through hole is provided with a first fixing member. The first operating unit further has a first opening. The first opening is provided with a first control member. The first operating unit is connected with an accommodating unit. The accommodating unit includes a telescopic rod therein. An outer peripheral wall of the telescopic rod is formed with a plurality of spaced first positioning holes corresponding to the first fixing member. The first fixing member is engaged in one of the plurality of first positioning holes for positioning the telescopic rod. Thereby, the telescopic adjustment of the telescopic rod is controlled by the first operating unit for articles of different heights, and the packing process is more smooth and convenient.

Method and apparatus are disclosed for drywall banjo tools for applying joint tape. An example tool for applying joint tape includes a base configured to couple to a drywall banjo that dispenses the joint tape. The example tool includes an arm including a proximal end and a distal end opposite the proximal end. The proximal end is rotatably coupled to the base to enable the arm to rotate between an extended position and a retracted position. The example tool includes a corner wheel rotatably coupled to the distal end of the arm to enable the corner wheel to apply the joint tape along a corner drywall joint when the arm is in the extended position. The example tool includes side wheels rotatably coupled to the base to enable the side wheels to apply the joint tape along a flat drywall joint when the arm is in the retracted position.
