A hand-tearable masking tape, comprising a plastic backing with a low adhesion backsize on the first major side of the backing and a pressure-sensitive adhesive on the second major side of the backing; wherein the second major side of the backing comprises a microstructured hand-tear pattern and wherein the low adhesion backsize comprises the reaction product of a mercapto-functional silicone macromer.

In a method for stretching a vapor deposition mask including a metal mask in which a slit is formed and a resin mask in which an opening corresponding to a pattern to be produced by vapor deposition is formed at a position overlapping with the slit, a stretching assistance member is overlapped on one surface of the vapor deposition mask, the stretching assistance member is fixed to the vapor deposition mask in at least part of a portion in which the one surface of the vapor deposition mask and the stretching assistance member overlap with each other, and the vapor deposition mask fixed to the stretching assistance member is stretched by pulling the stretching assistance member fixed to the vapor deposition mask.

The present invention provides a universal wheel spraying protection device, which is composed of a chassis, springs, a cone shaft, a tray, sliding blocks and composite tensioning sleeves. When the universal wheel spraying protection device is in use, a wheel is placed on a conical surface of an upper end of the tray, supporting springs are compressed by self weight of the wheel, and the tray is pressed down under the action of guiding columns and guiding sleeves; meanwhile, each sliding block drives the corresponding composite tensioning sleeve to move outwards under the action of the cone shaft; after a central hole is tensioned, the sliding blocks stops radial movement, and the tray also stops axial movement; and at this time, the central hole is protected by the composite tensioning sleeves, and a flange face is protected by the conical surface of the tray.

The invention is a device and method for forming a fade pattern on a large and/or compound-curved surface. The device and method each includes the creation and application of stencil panels to the surface, painting over the stencil panels, and then removing the stencil panels to leave a fade pattern. Also disclosed is a paint coating formed by a method according to the invention.

This invention generally relates to a painter's masking tape that covers well and is easy to tear in a straight edge without the use of scissors or other mechanical means. The tape comprises perforated portions that allow for the easy tearing of the tape. The bottom surface of the tape has an adhesive layer that is easily removed from the surface of the object to be protected. The non-adhesive portion is coated with an impervious coating to prevent the seepage of the paint or other liquid through the tape and onto the protected surface. The perforated portions of the tape are also made impervious to liquids by either being covered with an impervious coating, film, or tape pieces.

A bag constructed of a weed suppression material for packaging a ground cover material. When the bag is in a closed configuration, the bag serves as a container for shipping, handling, and storage of the ground cover material. When the bag is opened and unfolded, and the ground cover material within the bag is spread over the opened and unfolded bag, the bag serves as a layer of weed suppression material on top of underlying soil and beneath the ground cover. In addition, the bag may be used for planting individual plants in a planting bed, for establishing a buffer zone around the foundation of a building, or for controlling erosion around a downspout of a building.

A clamping apparatus includes a clamping frame, a first guide, a clamp, a linear driver, and a pressure sensor. The first guide is disposed on the clamping frame. The clamp is slideably engaged with the first guide, the clamp being configured to linearly move along the first guide to adjust a distance between the clamp and the clamping frame. The linear driver is connected to the clamp, the linear driver being configured to cause, at least in part, linear motion of the clamp. The pressure sensor is configured to sense pressure applied to an object clamped between the clamp and the clamping frame.
