What is the Function of Slitting Machine?

       The machine used for roll slitting is called a slitter rewinder, a slitter or a slitting machine - these names are used interchangeably for the same machines. Roll slitting, also known as log slitting or rewind slitting, is a shearing operation that cuts a large roll of material into narrower rolls. The log slitting terminology refers back to the olden days of saw mills when they would cut logs into smaller sections. They would also use these saw mills to cut iron rods into smaller sections. By today's definition, slitting is a process in which a coil of material is cut down into a number of smaller coils of narrower measure. Potential workpieces are selectively thin (0.001 to 0.215 in.) and can be machined in sheet or roll form. Slitting is considered a practical alternative to other methods due to its high productivity and the versatility of materials it can manage. Rewind slitting involves rewinding the material through a number of knives to form narrower rolls of materials.
       When the term "slitting machine" is used to describe the machine, the three parts are referred to as the unwind, the slitting section and the rewind. Slitter rewinders are normally used to slit plastic films, paper and metal foils. The unwind is normally braked to maintain accurate tension in the material. Some machines have a driven unwind which reduces the effect of inertia when starting to unwind heavy rolls or when the material is very tension sensitive. The slitting section has three main options: Rotary shear slitting, Crush cut slitting, and Razor slitting which is ideal for thin plastic film. The rewind section also has options. The main type is centre winding using differential rewind shafts.
       Roll slitting technique is heavily used by Converters industry. The converter industry normally refers to companies who print, coat and laminate materials. A typical converter is a company manufacturing producing flexible packaging material for packaging food. This may involve purchasing large rolls of plastic film such as biaxially orientated polypropylene (BOPP) which is then printed to the customer's design and coated with cold seal adhesive for use on high speed packaging machines. This material is printed and coated in wide, large diameter rolls for maximum efficiency. The rolls are then slit, using a slitting machine, into smaller rolls of the size to be used on the packaging machine.

As a cheerleader, how to deal with muscle tension?

       As we all know, cheerleading is not an easy sports! It’s one of the competitive sports. In western countries like U.S.A., there are hundreds of cheerleading competitions every year. From high school students to adult competitors, across America, you can find cheerleaders everywhere. Since it’s so popular, we have to be much more cautious about preventing injuries caused by this activity. Composed of tumbling, dance, jumps, stunting, and cheers such as throwing cheer bows or yelling slogan, cheerleading sometimes can be a dangerous sports. Therefore, people who want to take part in this activity must have some basic knowledge about how to prevent or treat injuries.
       Muscle tension injury is thought to be the common injuries caused by over-exercise. It is the continuous and passive partial contraction of the muscles. Unconscious nerve impulses maintain the muscles in a partially contracted state. If a sudden pull or stretch occurs, the body responds by automatically increasing the muscle's tension, a reflex which helps guard against danger as well as helping to maintain balance. Such near-continuous inner-invasion can be thought of as a "default" or "steady state" condition for muscles. There is, for the most part, no actual "rest state" insofar as activation is concerned. Both the extensor and flexor muscles are involved in the maintenance of a constant tone while "at rest". In skeletal muscles, this helps maintains a normal posture. When you practice too much, or become too nervous about the cheerleading competition, your whole body will become stiff. Therefore, the tension of your muscle will stretch too much and causes strain.
       In this case, one treatment option is heat and cold remedy. Cheerleader requires high amount of physical activity and sustained training (2 to 3 hours), causing muscle soreness, chronic pain or even strain. Strains, if not detected early to relieve or treat, may likely cause further injuries. To allow players to recover from muscular sores and chronic pain, using cold pack will relieve muscle discomfort as soon as it arises. It is the effective way for pain management. After the sore and swelling is better, then you can put on heating pad to ease the symptom. It is a pad used for warming of parts of the body in order to manage pain. Localized application of heat causes the blood vessels in that area to dilate, enhancing perfusion to the targeted tissue. Types of heating pads include electrical, chemical and hot water bottles.
       Many episodes of pain come from muscle exertion or strain, which creates tension in the muscles and soft tissues. This tension can constrict circulation, sending pain signals to the brain. Heat application eases pain by dilating the blood vessels surrounding the painful area. Increased blood flow provides additional oxygen and nutrients to help heal the damaged muscle tissue.

With Roll Slitting Equipment, You can Shear Materials Much More Efficiently!

       Also known as log slitting or rewind slitting, roll slitting is a shearing operation that cuts a large roll of material into narrower rolls. The machine used is called slitting machine. The log slitting terminology refers back to the olden days of saw mills when they would cut logs into smaller sections. They would also use these saw mills to cut iron rods into smaller sections; see slitting mill.

       For soft materials, there are several methods used for them. Razor blades, straight, or circular blades are being used. Some blades cut through the material while others crush the material against a hard roll. Those are similar to knives and cut the material into narrow strips, which are called coils when being rewound. The cutting blades can be set to a desired width. Some machines have many blades to increase the options of cutting widths, others have just a single blade and can be set to a desired location. The slit material is being rewound on paper or plastic cores on the exit side of slitter rewider.

       For harder materials, such as sheet metal, blades cannot be used. Instead a modified form of shearing is used. Two cylindrical rolls with matching ribs and grooves are used to cut a large roll into multiple narrower rolls. This continuous production process is very economical yet precise; usually more precise than most other cutting processes. However, the occurrence of rough or irregular edges known as burrs are commonplace on slit edges. Also, the geometry of these rolls is determined by specific tolerances in addition to the type of material and workpiece thickness.

Heal Your Sport Injury By Heating Pad

       Modern generation today prefer products for healing rather than medication. There are various products offered online for relieving muscle tension and are exclusively equipped with heating pad. These pads allow far-infrared waves to effectively reach deep tissues via resonance absorption. This boosts circulation which is the basic aspect of self-healing. When you browse the net, you will find various online websites dealing with pain management and offering products for healing. You can research online and grab a wonderful and cost-effective offer for dealing with your pain.

       Therapy is a famous form of treatment to alleviate pain and relieve a person’s mind and body. In addition, exercise has also proven out to be good for patients but working out in pain can complicate things further and that is not good. Pain management is needed to give timely treatment for a person who is hurting. Relaxation methods treated by physicians or online websites will be a good alternative as it can help a person to ease his pain and lessen the stress. But pain relief products such as using heating pad are popular these days not only for treating pain but also for preventing pain.

       Healthy living is based on everyday care and prevention. The specialist has found that current pain management programs tend to focus on treatment while ignoring prevention. The importance of prevention is often only appreciated after pain strikes or muscle tension occurs. Therefore, it is crucial to increase self-awareness regarding pain and to create a pain-free quality of living. By building on a foundation of preventative medical care and pain management, we can integrate people-oriented mentalities into healing products to provide new methods of household healthcare.
