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.

A film transfer tool has a case main body, a supply bobbin drive shaft driving a supply bobbin holding an unused transfer tape therearound, a take-up bobbin drive shaft driving a take-up bobbin taking up a used portion of the transfer tape therearound, a rotational coupling mechanism coupling the supply bobbin drive shaft and the take-up bobbin drive shaft together rotationally, and a reverse rotation preventive mechanism preventing a reverse rotation of the rotational coupling mechanism. The reverse rotation preventive mechanism has a rolling gear coupled to a rotational system made up of the supply bobbin drive shaft, the take-up bobbin drive shaft and the rotational coupling mechanism, moving gears moving over a predetermined range around the rolling gear and meshing with the rolling gear, and locking projections disposed to confront a reverse rotating direction of the rolling gear to lock the moving gears.

A press structure for a press type stationery, having mounting board (1), a button (400) and a resilient piece. The mounting board has a recess (11). A position limiting block (12) is provided at the front surface of the mounting board in this recess. A closed loop sliding track is formed between outer walls of the position limiting block and inner walls of the recess. The resilient piece has a spring (2) and a resilient rod (3). The position limiting block has a first inclined surface (122) and a second inclined surface (123). End portions of the first and second inclined surfaces are at one side of the resilient rod; upper ends of the first and second inclined surfaces are at another opposite side of the resilient rod. A contact part (4) positioned within the sliding track is provided at an upper end portion of the resilient rod.

A tape application and removal device for edge painting includes a frame, a pair of spools, and a roll of tape. Each spool is rotatably coupled to the frame proximate to a respective top corner of the frame. The roll of tape is positioned on one spool with the tape coupled to the other spool so that a section of the tape extends between the spools. The frame is configured to position the spools proximate to an intersection of a first surface and a second surface and to motivate the spools along the intersection so that the tape is applied to the first surface by the one spool and removed by the other spool as the spools are rotated along the first surface. The section of the tape is configured to protect the first surface from paint that is applied to the second surface between the spools.

The coating film transfer tool includes a feeding portion that feeds tape with a coating film, a transfer head that transfers the coating film from the tape onto a transfer target surface, a cassette to which the transfer head is fixed, and a head cap. Shaft portions are provided on either the head cap or the transfer head/cassette, and shaft bearing holes are provided on the other one. Due to relative rotation of the shaft portions, the head cap rotates between a closed position for covering the transfer head and an open position for exposing the transfer head. The distances from the rotation axis to the shaft portion and to the shaft bearing hole change along the circumferential direction. The head cap is biased toward the closed position when located on the closed position side, and is biased toward the open position when located on the open position side.

Apparatus and methods for manually applying flexible noodles (e.g., noodles made of adhesive material) to a workpiece (e.g., a composite part) during production or construction. The noodle is fed out over a series of upright rolls and rollers to the target area. Those rolls and rollers are rotatably coupled to a platform that is designed to be worn on the forearm of the operator. In accordance with one example, the noodle applicator comprising an ergonomic handle and an ergonomic forearm brace that are positioned and attached to the platform to allow the weight of the platform to be centered higher up the forearm, protecting the wrist. The direction of application is in-line with the forearm of the operator, decreasing the strain involved.

A dispensing device configured to operate with an adhesive backed mesh and backing film for tissue bonding is disclosed. The dispensing device provides for low-friction, low force pay-out of a desired length of an adhesive backed mesh to a wound site. The device prevents or eliminates distortion of the mesh prior to application to the wound site, and includes means for reducing or eliminating binding during use. The dispensing device is configured to operate in a forward mode (substrate to which mesh is applied passes beneath applicator after mesh is applied) to provide essentially an unobstructed view of the wound site during use.

Method and apparatus are disclosed for drywall banjo tools for applying joint tape. An example drywall banjo for applying joint tape includes a banjo body. The banjo body includes a panel and side walls protruding from outer edges of the panel to define a cavity that is configured to contain joint compound mud. The side walls include a first side wall that extends between an inlet and an outlet. The example disclosed drywall banjo also includes a sloped mound configured to couple to and project away from the first side wall within the cavity. The sloped mound is configured to guide the joint compound mud within the cavity toward the joint tape travelling between the inlet and the outlet to enable the joint compound mud to uniformly collect on a side of the joint tape.

The cleaning device provided in the present disclosure includes a housing, the housing includes at least two housing units formed by sectioning the housing, and two adjacent housing units are detachably connected with each other. The housing is provided with a storage device, a recovery device, and a liquid-supplying device; an opening is arranged on the housing and a guide head is provided in the opening. The storage device stores a cleaning cloth, which is drawn out of the storage device and extends out of the housing via the opening, and which extends into the housing via the opening after going around the guide head and is then connected to the recovery device. The recovery device is configured to draw the cleaning cloth to the recovery device to recover the cleaning cloth.
