Abstract: A hinge conveyor chain includes at least two links, each of the links include a pin engaging surface for engaging a pin hingedly coupling the at least two links together. A pin hingedly coupling the at least two links includes an outwardly facing surface slidably engaging at least one of the pin engaging surfaces of the at least two links. One of the outwardly facing surface and the at least one pin engaging surfaces of the at least two links is formed from a steel alloy with at least about 2.5 wt. % Cu and the other of the outwardly facing surface and the at least one of the pin engaging surfaces of the at least one of the at least two links is formed from a stainless steel.

Abstract: An improved apparatus for tensioning embroidering fabric between frames has an outer frame half template mounted to a frame assembly so as to maintain alignment with an inner frame half template when the table assembly holding the fabric is repositioned. The inner frame half template holds different sized inner frame halves which can be aligned with corresponding outer frame halves by adjusting the position of locator pins in the inner frame half template. The outer frame half template is adjustable to accommodate circular outer frame halves of different sizes while maintaining a common center point.
