Abstract: A stack of strips of feed stock are placed on an adjustable height table. The strips are positioned on the table by arms which align the stack to the centerline of punching dies in a punch press. A pneumatic actuated head uses vacuum cups to raise the end of the top strip and insert it into in-feed rolls. The drive means for the in-feed rolls also drive an encoder which signals roll movement as the rolls incrementally feed the stock into the punch press. Drive means for the feed stock switches to the out-feed rolls once the blanked out stock reaches those rolls, and when the end of the strip passes through the punch press, a control unit is signaled and a new strip is fed into the system.

Abstract: Automatic loading device for automatically positioning of panels of sheet metal or the like and to transfer the panels to a feeding device of a machine tool, preferably a cutting press. The cutting press cuts a plurality of blanks out of the panel along a given pattern which is stored in a program. The program is controlling the cutting press and the feed device in synchronism in order to provide the blanks, e.g. lids for cans within minimum production time. The time when the loading device is working overlaps the production time for the preceeding panel, i.e. the aligning of the panel in the loading device took place when the preceeding panel is cut. As soon as the feeding device returns to the zero position the loading device transfers the next panel to the feeding device, the panel maintaining its precise aligned position. The feeding device starts to a new feed cycle.

Abstract: A stock feed and shear system which may be utilized in an automatic ticket vending machine for cutting tickets from different rolls of stock and delivering the tickets to other components such as a printer and a magnetic encoding transport. The rolls are supported on reels having releasable clamp mechanisms for allowing rapid replacement of spent reels while providing a predetermined drag between the roll cores and the reels. The reels are spring loaded so that stock can be unwound from the rolls only by positively driving the same with selectively driven pinch rollers. Guide tracks direct the stock to a rotary shear which cuts single ticket lengths from the stock without metal to metal contact, thereby achieving excellent service life. Sensors provide an indication of spent rolls, completion of a cutting operation, and presence of a ticket in the shear. In another embodiment paper or plastic tickets are pre-cut by a two-way rotary shear and are held in escrow.

Abstract: Apparatus for subdividing a web of wrapping material into sections of predetermined length has a reciprocable carriage for a pair of grippers which are pivotable into engagement with the web to thereby clamp the web against the carriage while the latter moves forwardly. This advances the web through a distance which approximates but is less than the distance necessary to advance the web by the length of a section. The grippers are thereupon disengaged from the web while the carriage continues to move forwardly, and the web is braked by one or more brushes so that two pawls whose pallets are biased against the web can catch up with a pair of marginal notches in the web. The pallets enter the respective marginal notches and complete the forward movement of the web. A mobile knife cooperates with a stationary knife to sever the web and to thus separate a section from the leader of the web while the carriage moves rearwardly.

Abstract: A continuous cold cut slicing system utilizing a slicing machine having a conveyor which feeds a loaf into engagement with a series of drums located on each side of the slicing machine channel; the drums are driven by a variable speed motor with the rotation of the drums providing a feed mechanism of the product to the slicing blade. A gripper assembly is provided which rides on a guide shaft adjacent the channel with the movement of the gripper in the channel constantly being monitored by an encoder and clutch arrangement connected thereto. As the gripper approaches the knife, the encoder and clutch arrangement provide for a drag on the gripper thereby controlling the feed of the product compensating for pull on the knife. Also, since the encoder and clutch arrangement are constantly monitoring the position of the gripper the exact location of the tail end of the loaf being sliced is readily determinable so that a profile compensation control system may be effectively incorporated into the system.
