Binder cutter. Tips for the home master

Builder, home master

The device that I use with success for home bookbinding - whether an old book is being restored, or a filing is being done - consists of practically two main parts. These are a kind of wooden vice (press), where a cut block of paper or cardboard is clamped, and a block with a knife clamped in it. To make both is available to everyone, and this will not require any special tools, or scarce materials, or a lot of time.

Binder Cutter
Assembly trimming device: 1 - block, 2 - sliding platform, 3, 4 - bars of the press (vice), 5 - block, 6 - knife, 7 - tightening bolt, 8 - gasket (cardboard)

A vice (press) is any two bars with holes for the bolts tightening them. The cross section of the bars should be such that when the cut block is clamped between them, they do not bend (approximately 60x60 mm), and the length - depending on the format of the book or binder: the cut blocks must be placed between the tightening bolts. This can also be recommended for bolts - to select them of such a length that it is enough for both bars and the thickness of a possible block, that is, with a margin. Tightening nuts are better to use wing nuts.

A plastic (viniplast, getinaks) or metal plate is attached to the side plane of one of the bars - a sliding platform for a block with a knife.

The block itself somewhat resembles a planer: there is a wooden case, two handles, a piece of iron (knife); and its movements during pruning are similar. The most important detail is the slot for attaching the knife. It is formed by two overhead metal strips, the edges of which are beveled so that a groove is obtained for inserting a knife, respectively processed along the edges. To fix it in the socket, a nut is sunk into the block and a bolt is omitted, pressing the knife.

Shoe: 1, 3 - socket plates, 2 - knife, 4 - body, 5 - handle, 6 - nut, 7 - clamping bolt

Working with the device is extremely simple, although it requires some caution. A vise-press is installed on the edge of the table with a cutting block clamped in them (the side to be cut is up). A block is laid on the sliding platform with a knife to the block to be cut. On the opposite side of the block, plywood or thick cardboard should be placed, which will “take over” the knife after it cuts through the last layer of the block.

Cutting movements can be almost effortless: the knife cuts the block neatly and cleanly, layer by layer.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

10000 PPI OLED display 01.11.2020

Display pixel density may not always be clear to users. For example, the density of 800 PPI is 2 times higher than the density of 400 PPI, but it cannot be said that the difference is noticeable to the eye, especially when it comes to smartphone displays.

In fact, high pixel density is important in cases where the display is placed close to the human eye, such as in virtual reality headsets. In such devices, the displays are located literally centimeters from the eyes, and individual pixels can be noticeable even if the density index exceeds 500 PPI.

To overcome this problem, Samsung researchers and colleagues at Stanford University have developed a new type of OLED display that has a pixel density of 10000 PPI. The display uses light resonance technology. Its concept is the same as sonic resonance, such as when the body of a guitar resonates with the strings to create sound. In this case, light resonates at the nanoscale between two specific surfaces, creating different color tones from the OLED white light source. With this method, the researchers were able to efficiently create really tiny colored "pixels".

So far, we are talking only about a laboratory prototype. It is not specified when displays based on this technology can be launched into mass production. But when (or if) it does, it could revolutionize the OLED display industry, leading to immersive virtual reality technology, TVs and smartphone displays with incredible pixel counts.
