Machines Rectilignes Manuelles

• Conception Machine Jersey: The machine is designed with a needle bed (fonture) for Jersey knitting. Parallel grooves in a metal plate hold the needles. A cam plate moves needles in their grooves using a guide-pin. A pulling system is needed to drop stitches.

Fonture

• Description: A metal plate (fonture) with parallel grooves (2) to hold needles (1). A covering plate (3) prevents needles from moving up too much. Each space between consecutive needles has a partition called a "cloison" (4) with a top tooth, the "dent d'abattage" (5). These teeth make up the "peigne d'abattage."

• Function: Provides precise placement of needles for knitting. The distance between needle axes, called the "division", defines the gauge, measured in millimeters per specific number of needles (division).

• Two Gauge Systems: A "direct system" or "Swiss gauge" measures millimeters per 10 divisions, effectively measuring divisions' decimals. There is also an "inverse gauge" system, which is used in other regions.

Plan de cames

• Mechanism: The needle movement uses inclined planes and a movable carriage. The carriage moves the cams for raising and lowering needles to make fabric. The carriage holds the "came d'ascension" (lift cam) and "cames de chute" (drop cams).

Cames d'Ascension et de Chute

• Ascension: A triangular cam with a pointed tip that lifts the needles upwards.

• Chute: Two triangular cams with a downward pointed tip that move the needles down.

• Adjustment: The cams can be adjusted (e.g. different heights/positions) on the cam system

Réglage des cames

• Definition : The ability to adjust the cams to control the depth of the needle's movement. Adjustment of cams to help create precise stitch patterns. This often means adjusting the angle of the cam.

•  Types: “noyer” type (adjustable) cams which can be set in different positions for precise needle movements. Different positions yield different outcomes (e.g. moving stitches from left to right.)

Réglage des Cames de Chute

• Purpose : The position of the drop cams controls the stitch length, influencing the "serre" (tightness) of the fabric. The adjustment of these cams, impacting the depth at which needles drop down.

Passage du fil

• Mechanism: The thread travels from the spool to the needles, passing through guides and tensioning mechanisms (tension control). The exact path guides the thread to the needles.

Système de Tirage

• Mechanism: This system provides consistent thread tension to guide threads to the needles. Tools include a plate "le peigne de montage" and weights "poids" to pull the stitches apart for the assembly of work. Weights adjust the strength of the stitch pull.
