Some reels or skein winders are made without the gear mechanism (see swift (textiles)). They perform the same function, but without the "clock" or pop to aid the spinner in keeping track of the length of thread or yarn produced. A niddy noddy is an even simpler version.
Alternatively, a sheave can be integrated and installed within the housing frame. In this case, the system can be set up anywhere around the drum. Oceanographic installations that spool rope up to 46 layers have demonstrated that level winders give synchronized and controlled spooling in the harshest, most testing conditions.
35mm film reels and boxes 16mm empty film reel with its metal container It is traditional to discuss the length of theatrical motion pictures in terms of "reels". The standard length of a 35 mm film reel is 1,000 feet (305 m), which runs approximately 11 minutes for sound film (24 frames per second ) [ 2 ] and about 15 minutes for silent film ...
Parts of a spinning reel: 1: Pick up or bail 2: Reel seat 3: Reel foot 4: Handle 5: Support arm 6: Anti-reverse lever 7: Skirted spool 8: Fishing line 9: Drag adjustment knob A fishing reel is a hand- cranked reel used in angling to wind and stow fishing line , [ 1 ] typically mounted onto a fishing rod , but may also be used on compound bows ...
Long, angled splices can also be used to create a perceptible dissolve from one sound to the next; periodic segments can induce rhythmic or pulsing effects. [5] The use of reels to supply and collect the tape makes it easy for editors to manually move the tape back and forth across the heads to find the exact point they wish to edit.
Diagram of bar drawing; the workpiece is pulled from left (tension) rather than pushed from the right (compression). Drawing is a manufacturing process that uses tensile forces to elongate metal, glass, or plastic. As the material is drawn (pulled), it stretches and becomes thinner, achieving a desired shape and thickness.
The size of the spool and the thickness of the line together determine the length of line the reel can hold, though this is also affected by how neatly the line is wound onto the spool. [4] The winding knob is on the side of the spool. Most reels are laid out for holding in the left hand and winding with the right.
Film is commonly checked for broken sprocket holes before presentation, a process known as "spooling". Mechanical devices exist for this purpose, but the classic method is to place the finger and thumb of a gloved hand on the edges of the film, which is mounted on a winding bench, and to slowly run the film through the fingers, feeling for snags.
