![]() Warehouse of Reed Tongues: The photo shows the wooden drawers These moulds need constant upkeep and control to assure high quality cutting of the reeds tongues, with very exact tolerances (hundred mm) being constantly checked. ![]() While reeds plates in soft aluminium are ready to be assembled, reeds plates in Duraluminium for TIPO A MANO (hand type) or A MANO (hand made) reeds must also be filed inside the holes to guarantee maximum precision.Ĭutting of Reeds Tongues: The ground reed plates and the ground small strips/bands are cut with special moulds made of extremely hard steel. 16 tongues) or in small strips / band (two tongues each for A MANO - hand madeĬutting of Reed Plates: With special moulds, the reed plates are cut from an aluminium sheet (which can be a hard or soft aluminium type) complete with holes for the tongues and rivets. Adequate grindstones together with a special technique are necessary to avoid steel overheating and to retain the sound quality of the metal. The Grinder: This is a most important production phase. To be considerated as WELL DONE, on bending the tongue, it has to show a round homogeneous and slim curve. The photo shows the filing by hand of the shape, working on a tolerance of hundredth millimetre. To each single reed belongs its best profile in terms of hardness and shape, to guarantee the best quality sound output. The Research for a Better Profile: Each note has its own profile there are over 400 different notes as they have many scales, types and sizes of reeds in production. This photo shows the metal shape on which the tongue profile is ground. This shape will direct the grindstone, so it will remove the steel from the tongue to achieve the required tongue shape. To carry out this operation, a carefully designed profile must be set up on a metal shape. To have a steel tongue produce a note, it is necessary to shape the profile of the tongue by removing material. The Profile of the Reed Tongue: The Harmonic steel precision strip (which must have special features referring to hardness and ductility) is the raw material for the reed tongues. This visit using photographic images from an Italian factory, which has produced reeds since 1935, is intended to show the production steps in the manufacture of this most important component of the accordion. ![]() Other reeds sound only satisfactory, and there are also reeds which produce an unsatisfactory sound. There are reeds which sound beautiful and improve, the longer they are played. The basic materials of the reed are a plate, two tongues, two rivets, and into these materials must be added a lot of work and a wealth of skilled experience. ![]() Behind this intention is the belief, that the more profound the knowledge of the product, the more this helps clients to choose with care the instrument best suited to their needs, increasing satisfaction to the purchaser and performer. The purpose and aim of this initiative is to contribute in the spread of knowledge to accordion lovers and people interested in this wonderful instrument.
