A system is disclosed for ensuring that the pod door is firmly and securely retained on the port door of a process tool as the pod door is removed from the pod and stowed in the process tool during workpiece transfer between the pod and process tool. The system includes a latch key protruding outwardly from the outer surface of the port door. The latch key is provided to mate within a slot of a door latch assembly within the pod door. Once the latch key is properly seated within the slot, the latch key is rotated by mechanisms within the port door to decouple the pod door from the pod shell. Such rotation at the same time couples the pod door to the port door. According to the present invention, while the latch key rotates, it simultaneously moves in the rearward direction (i.e., back toward the port door) to thereby pull the pod door into a tight engagement with the port door.

The device according to claim 1, wherein the lower column part includes a transport device. the base on the instrument, said connector including: a rod receivable through the first aperture; a lug engaging mechanism disposed at one end of the rod for engaging the lug; and a locking mechanism disposed at the other end of the rod, said locking mechanism being adapted to lock the lug engaging mechanism in position once it has engaged the lug. 17. A support as defined in claim 16, wherein the lug engaging mechanism is a hook. 18. A support as defined in claim 16, wherein the base defines a second aperture and the accessory holder comprises a shaft at least partially mounted within the second aperture in the base, the shaft including a mechanism for securing an accessory thereto. 19. A support as defined in claim 18, further comprising a shock absorber disposed between the shaft and the base. 20. A support as defined in claim 19, wherein the shaft and shock absorber are held by friction within the second aperture. 21. A support as defined in claim 16, wherein the locking mechanism comprises a lever, and when the lever is rotated in a first direction the lug engaging mechanism is moved closer toward the first surface of the base, and when the lever is rotated in a second opposite direction the lug engaging mechanism is moved further away from the first surface of the base. 22. A support as defined in claim 16, wherein the locking mechanism may be locked so as to keep the lug engaging mechanism engaged with the lug. 23. A support for attaching an accessory to a drum, the drum having a side and at least one lug, the support comprising: a) a base having a first surface; a second surface, the base defining an aperture and defining a bore extending from the first surface through to the second surface, the aperture and the bore being a spaced distance from each other; and the second surface further having a channel defined therein; first and second legs extending from opposite ends of the first surface, the first and second legs being adapted to engage the side of the drum; b) a lug engaging mechanism having: a rod which is at least partially received in one of the aperture and the bore; a hook disposed at one end of the rod so that the hook lies between the first and second legs of the base; a locking mechanism disposed at the opposite end of the rod; the locking mechanism including a layer which is at least partially received within the channel in the second surface of the base, the lever being rotatable between locked and unlocked positions, the locked position drawing the hook closer to the first surface of the base and the unlocked position moving the hook further away from the first surface of the base; c) an accessory holder mounted on the base, the accessory having: a shaft which is at least partially received within one of the aperture and the bore of the base, the shaft having a mechanism for securing an accessory thereto; and a shock absorber disposed between the shaft and the base, the shaft and the shock absorber being held by friction within the bore. 24. A support for attaching an accessory to an instrument; the instrument having a surface and a lug; the support comprising: a base adapted to engage the surface of the instrument; an accessory holder attached to the base; and attachment means mounted on the base and adapted to engage the lug of the instrument and hold the base on the instrument. 25. The support of claim 24, wherein the attachment means includes a device that forces the base against the surface of the instrument. 26. The support of claim 24, wherein the attachment means includes means for creating a tensile force in the attachment means. 8356, 19920100, Adams, 248/206.2; US-5087005, 19920200, Holoff et al., 248/205.8; US-5104077, 19920400, Liu, 248/205.8; US-5402974, 19950400, Adams, 248/205.5; US-5592244, 19970100, Vyhmeister, 351/158; US-6180115, 20010100, Conrard et al., 424/400; US-6193197, 20010200, Lian, 248/206.2 is a circular-shaped, two-armed actuating lever (45) that is pivotally mounted between roller discs (43, 44) of the transfer roller (18, 19), with one end of the actuating lever (45) interacting with the suction head (20) and the other end of the actuating lever (45) interacting with the pressure lever (52). 10. Apparatus according to claim 9, characterized in that there are a distal transfer roller (18) and a proximal transfer roller (19) arranged at a distance from one another in the axial direction and the shaft (61) serves to supply the suction heads (20) of transfer rollers (18, 19) with a suction pipe (64), the suction pipe (64) being arranged in concentric fashion within the shaft (61) and being associated with the distal transfer roller (18) and with a ring channel (65), which encircles the suction pipe (64)and is associated with the proximal transfer roller (19). 11. Apparatus according to claim 1, characterized in that, for two-track operations, two blanks magazines (14, 15) are arranged at a distance from one another which corresponds to the space between two blanks paths (17) connected to the blanks magazines (14, 15) or to the distance between two pockets of a folding turret. 12. Apparatus according to claim 11, characterized in that each blanks magazine (14, 15) is associated with at least one transfer roller (18, 19) and that all transfer rollers (18, 19) are mounted on shaft (61), and can be moved by same.
