1. Masking paper: suitable for small roll core masking paper (the inner diameter of the paper core is about 38mm), the width of the masking paper is 50mm (1cm=10mm=1 cm) 2. Main body: made of glass fiber reinforced engineering plastics, designed, strong and durable; 3. Roller: Built-in two industrial-grade bearings, outsourcing wear-resistant buffer rubber, smooth rolling, close to the side of the inner corner when in use, to achieve precise positioning and guidance; 4. Knife saw: It adopts special-shaped oblique incision design, made of stainless steel, and can easily cut off the tape; 5. Pressure wheel: built-in two industrial-grade bearings, outsourcing wear-resistant buffer rubber, rolling smoothly, when in use, stick the tape tightly to the working surface of the inner corner; Stop block: limit masking paper to prevent drifting; Limiting baffle: Then through a single or a combination of two limiting baffles, snap it into a suitable card slot to locate the position of the tape (this function can be used or not used according to needs); Tape runner: Made of glass fiber reinforced engineering plastic, adopts snap-in design, fast loading and unloading of masking paper, the distance between the tape and the root of the inner corner can be adjusted from 0 to 50mm; Handle: Ergonomic design, grip feeling, easy to operate; Adjustment nut: Rotate the cross screw in the hole to adjust the damping of the rotation of the tape wheel to adapt to masking paper with different toughness and thickness; Name: Corner Paster Applicable masking paper width: ≤50MM Spacing adjustment range: 0-50MM Masking paper length: ≤50M It should be pointed out that the internal corner sticker itself is positioned as a kind of internal corner pasting tool, but it does not mean that it is only applicable to the internal corner area
