Generally, a covered cotter of dressers is configured to be folded in four directions from an axial rotation at its center. And, the Cotter Cot also is configured to include a concealed cutting wheel positioned to an exposed edge of an opposite side of an opposite edge of the same side of the rotating center axis of this particular Cotter Cot (axis). The concealed cutting wheel is positioned in a spot that can be easily accessed by all members of the household who will use the Cotter Cot for the purpose of placing articles into the Cottery for later storage. Usually, the hidden cutting wheel is placed in a drawer (or sometimes, within a wall panel) within the Cottery. However, some designs of Cotters have the concealed wheel positioned on the opposite side of the opposite edge of the Cotter Cot and so, it is exposed when the Cotter Cot is folded. This Cottery is often used in attics or closets, wherein the size of the Cottery is smaller so, there is need to make some arrangement for the wheels to get access to.
A tip dresser is usually built with four metal contact rails positioned around its entire circumference. These contact rails are made with small plates with flat contact points at their end, which are capable of facilitating electrical impulses as they are pushed by way of a spring. As they are pushed, they allow a series of cutting paths for the electrical impulses and thus, provide the Cotter Cot with four different levels of movement. All the Cotter Cot models may be configured in several different configurations depending on the model’s specifications and the degree of its several modes of movement.
All the four major types of Cotter Cots that are widely available have some similar characteristics but, there are also differences. The most common among these variations is the manual tip dresser and the automated one. With a manual tip dresser, it is the job of the user to manually control the rotation of the contact rails, which in turn, helps in the cutting or changing of the tip. For an automatic one, all you need to do is to set the settings manually by means of a switch or a knob. Another difference is the type of voltage that is required for the automatic one and the manual one.
The main difference between a manual and the automated one is that in the former, you will have to manually control the rotation of the four contact rails whereas, in the latter, you can let the robot do the work for you. The other important characteristic is the amount of voltage required for the tip dresser according to the present invention. The voltage needs to correspond to the operational level of the robot. It means, that if the robot has been programmed to perform certain tasks then, it should be able to do so according to the appropriate voltage level.
Another feature of Tip Dresser according to the present invention is the shape of the cutter body. In case of manual tip dresser, it is made up of circular plates that are attached to each other. This cutter body is called the contact surface. However, with the help of robots, the shape can be changed into various other shapes like flat plate, cylindrical body etc. All this results in the variation in the cutting width of the appliance.
The six bores are generally placed in the contact surface of the cutter. The presence of these six bores in the contact surface allows the robot to move freely on the surface. The other feature of Tip Dresser according to the present invention is its precision engineering. In the manual dressers, the depth of cut could be as much as 0.2mm; however, with the help of this invention, the depth of cut can be increased up to six times as compared to that of manual dressers. The present invention basically deals with accuracy in cutting the six curved edges of the blade by means of six rotating cutting tools.
