Abstract
A cloth spreading apparatus 10 for spreading cloth from a cloth roll 16 supported by an expandable mandrel 20 onto a work surface 14. The apparatus includes a carriage assembly 24 movable on the work surface between first and second locations. A mounting frame assembly 26 is carried by the carriage and includes a shiftable subframe 118, 120, 122, 124, 126 and 128, a first pivotal portion 94 supported on the subframe and a second portion 96 rotatable 180.degree., the second portion being carried by the pivotal portion. A shifting motor 74 is provided to shift the subframe in response to a cloth edge sensing apparatus 58. A motor driven screw operated scissors jack assembly 102 is provided to pivot the pivotal portion. A cantilevered spring 200 is disposed between the pivotal portion and the rotatable portion and initially accelerates and then decelerates the rotatable portion as it moves 180.degree. from one position to another. An electric prefeed motor 210 drives an output gear 208 engageable with a spur gear 212 on the mandrel, the motor prefeeding or dynamically braking the cloth roll assembly in response to cloth tension sensing means 66 on the carriage assembly.
