An apparatus, system and method for grinding or polishing an optic is provided. The apparatus includes a shell adapted to a bending profile, torque actuators attached at an outer edge of the shell and coupled to each other, a tensioning system attached at the outer edge of the shell, and a control system for computing the bending profile and controlling the torque actuators and tensioning system. The torque actuators and tensioning system apply bending moments to the edge of the shell to adapt the shell according to the bending profile provided by the control system. A calibration system further corrects errors in a measured bending profile.

Lap grinding and polishing machine

In winding methods, a primary nip formed against a web defines continuing and leading web portions. A secondary nip is formed against and moved along the leading portion, from an outfeed side of the primary nip to an infeed side. The continuing portion and a free end of the leading portion are then simultaneously advanced into the primary nip. Winding apparatus has a winding spindle and builder roller that rotate about parallel winding and builder roller axes, respectively. An axle defines a guide axis and carries a cinch roller that rotates about the guide axis. The axle pivots between first and second orientations, in which the guide axis parallels and is transverse to the winding axis, respectively. The axle moves in the first orientation, in an incomplete orbit about the winding spindle from a start to a rotated position, both adjacent the builder roller, and returns in the second orientation.

Web winding apparatus having traveling, gimbaled cinch roller and winding method

A web (14) of material such as photographic film is supplied continuously from a stock roll (16) into an infeed vacuum box (24) from which the web passes into an intermittently operated perforator apparatus (30) through which the web is drawn intermittently by a high performance vacuum drum (32) which feeds the web into an outfeed vacuum box (34) from which the web passes continuously to a rewind stock roll (44) or to other intermittently operated processing apparatus. Various patterns of widely spaced perforations and leader/trailer sections may be provided in the stationary web, which moves at high web speeds and accelerations between operations of the perforator apparatus.

Apparatus and method for transporting and perforating enlongated strips

A pair of skewers (540,542) are slidably mounted to a frame (516-534) and connected to a mechanism (538) which can move the skewers toward and away from each other to position or release an object such as a spool (10), the mechanism including a crank member (580), a U-shaped link (544) connected between one skewer and the crank member, a cam plate (572,574) connected between the other skewer and a cam follower (590) carried by the crank member, so that rotation of the crank member causes the skewers to toward or away from each other.

Apparatus for positioning a spool or similar object

An end cap staking apparatus comprises a frame (28) with a slide rail (34) on which a staking mechanism is slidably mounted, the mechanism including a base plate (32) from which a mounting flange (72) extends, a quill shaft (82) supported by the mounting flange, a pivot ring (92) mounted on the free end of the quill shaft, a plurality of elongated staking fingers (102) pivotably supported between their ends around the pivot ring, an outwardly flaring portion (110) on one end of each staking finger, a cam follower (118) on the opposite end of each staking finger, a cam (88) engaged with the cam followers and an actuator (130-158) for the cam to move the flaring portions radially for staking.

Apparatus for staking end caps onto a cylindrical shell

An apparatus and method are disclosed for forming a very open shell (28) having axially extending lips (20c,20t) spaced sufficiently far apart to permit a prewound spool of web material (10) to be inserted radially, laterally into the very open form shell, after which the shell is closed and end caps (24) are installed. Apparatus are disclosed for forming the very open form shell (40), transferring the shell to a mechanism for applying end caps (48), inserting a prewound spool of web material (56) into the very open shell, positioning the spool accurately within the shell (780-856), closing the shell about the spool (58) and staking the end caps in place (60).
