Sheet Feeder Cantec supplies a range of sheet-feeding systems perfectly suited for your applications. Straight feeder for straight-sided and scrolled sheets or coil feed (operating without idle strokes) Single zig-zag sheet feeder for straight-sided and scrolled sheets (operating with idle strokes) Double zig-zag sheet feeder for straight-sided and scrolled sheets (operating without idle strokes) Straight-sheet or coil feeder The Servodrive roll feed mechanism guarantees measured precision feeding The roller feed mechanism is controlled by servomotors that generate highly precise advance movements with accurate, non-cumulative positioning. A digital servo controller ensures feed profiles with optimum acceleration, enabling smooth, non-slip acceleration for thin materials. Sheet alignment Sheets are centered by alignment wedges at the scroll. Straight-sided sheets have three-point alignment. The END-O-MAT for double-row tooling is equipped with a roller feed mechanism at the infeed. This roller feed mechanism has been specially dened to process thin materials, with adjustable pressure and a pressure roller with optimized mass moment of inertia. High feed precision and, consequently, the smallest possible web width are achieved by means of a precisely ground feed-controlling upper roller and a highly-dynamic servo-drive. The drive is controlled by an intelligent, fully digital servocontrol which allows acceleration-optimized feed profiles to be set. The relatively thin sheet can thus be accelerated, decelerated and positioned smoothly and without jerks. This feature is of special importance for conveying of the sensitive scrap skeleton in particular. Therefore the roller feed mechanism at the discharge is of similar den, but with special emphasis on careful transport of the scrap skeleton. The feed precision of both roller feed mechanisms is better then 0.05 mm. Flow of material through the END-O-MAT with double-row tooling: Some advantages and specific features of the process are best described by describing the flow of material through the END-O-MAT. A linear feeder, which is controlled by a servomotor, lifts the uppermost sheet from the stack by selfregulating suction units and transfers it to the point of infeed. Alignment wedges centre the sheets at the scroll. Correct alignment is monitored by proximity switches. Alignment at the scroll does not require the sheets to be of exact width and has a higher tolerance of deviation from angularity. Sensors are monitoring the alignment. In case of misalignment, the machine automatically carries out two more alignment attempts. If correct alignment of the sheet is still not possible, the machine is stopped and displays a fault alarm.

A double sheet detector and a sheet lacquering monitor system are part of the scope of supply. Detection of double sheets or any faulty lacquering on the top or bottom side of the sheets causes the controller to stop the machine to avoid scrap or damage to the tooling. The lacquering monitor system can be switched off if unlacquered sheets are to be processed. To compensate for sheet length variations the machine is supplied with a sheet length compensation system. Sensors measure each sheet. The measured dimensions are compared with those of a reference sheet and provide the data required...

Tooling system Multi-die tooling makes FEA-optimized end designs a reality. Boosting productivity and product quality depends to a large extent on easy accessibility to tools and rapid die set change. The END-O-MAT’s quick-lift function provides fast, convenient access to the die area at the comfortable height of 1400 mm ( 55” ). Spring-loaded rollers, which lift the tooling from the slide plate once the fixing screws have been loosened, allow the tooling to be changed swiftly and simply by a single operator using a special tooling carriage. END-O-MAT multi-die tooling The individual tools...

Multi-stage tooling Cantec’s multi-stage tool is the system of choice for critical shells. The production sequence consists of cutting the blank, drawing the inner panel in several stages (the number of stages depends on the profile), and forming the countersink without tensile forces from the inner geometry. Production of top and bottom ends is geared to optimum performance as regards buckle, distension, vacuum pull back, and lacquer-preservation in material grades from SR material to the hardest DR material (in the latter case, twisting is reduced to a minimum). The thinning of material...

END-O-MAT Accessories the END-O-MAT system includes a range of Optional extras that make all the difference to your budget Tool-changing carriage for smooth handling The tool-change carriage allows tooling to be removed and installed by just one person in a matter of minutes. Remote diagnosis Access to the machine controls via phone line facilitates checking the settings. Sheet lubricating system A spraying or rolling system is available for lubricating the sheets in special cases. Oil temperature control In extreme climates, this system heats and cools the oil to ensure constant oil and...
