Crimp (joining) in the context of Cartridge (weaponry)

A ferrule (a corruption of Latin viriola "small bracelet", under the influence of ferrum "iron") is any of a number of types of objects, generally used for fastening, joining, sealing, or reinforcement. They are often narrow circular rings made from metal, or less commonly, plastic. Ferrules are also often referred to as eyelets or grommets within the manufacturing industry.

Most ferrules consist of a circular clamp used to hold together and attach fibers, wires, or posts, generally by crimping, swaging, or otherwise deforming the ferrule to permanently tighten it onto the parts that it holds.

A fastener (US English) or fastening (UK English) is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel.

Other methods of joining materials, some of which may create permanent joints, include: crimping, welding, soldering, brazing, taping, gluing, cement, or the use of other adhesives. Force may also be used, such as with magnets, vacuum (like suction cups), or even friction (like sticky pads). Some types of woodworking joints make use of separate internal reinforcements, such as dowels or biscuits, which in a sense can be considered fasteners within the scope of the joint system, although on their own they are not general-purpose fasteners.

A jingle bell or sleigh bell is a type of bell which produces a distinctive 'jingle' sound, especially in large numbers. They find use in many areas as a percussion instrument, including the classic sleigh bell sound and morris dancing. They are typically used as a cheaper alternative to small 'classic' bells.

The simplest jingle bells are produced from a single piece of sheet metal bent into a roughly spherical shape to contain a small ball bearing or short piece of metal rod. This method of production results in the classic two- or four-leaved shape. Two halves may also be crimped together, resulting in a ridge around the middle. A glass marble may also be used as the ringer on larger bells.

Multipart stationery is paper that is blank, or preprinted as a form to be completed, comprising a stack of several copies, either on carbonless paper or plain paper, interleaved with carbon paper. The stationery may be bound into books with tear-out sheets to be filled in manually, continuous stationery (fanfold sheet or roll) for use in suitable computer printers, or as individual stacks, usually crimped together.

The purpose is to produce multiple simultaneous copies of a document produced by handwriting with a pen that applies pressure, such as a ballpoint pen, or with an impact printer. The pressure of writing or impact printing on the carbon or carbonless paper transfers the content to the copy sheets. Depending upon requirements, up to typically four copies of the original can be made, with the quality and readability decreasing towards the bottom copies. This type of stationery can be used whenever multiple copies are required, of quality adequate for the purpose, usually noticeably inferior to, for example, laser-printed output. Typically a company may need a document such as an invoice to give to a customer (original), with a copy for their own accounting department (first copy), and possibly further copies for other purposes. The paper stock used is typically of low weight—thin—to transfer more printing pressure. The different copies can be on paper of different colour to distinguish them, and preprinted content may vary between copies.
