oVerVieW the fully automatic, continuously running machinealPha i in rotary turret design is used for the further pro-cessing of press-twist (pt) caps and other closures.

a lining compound is introduced into tinplate caps and molded under the action of heat and pressure.

The individual operations are:

• cap feeding

• separating and transferring the caps using index stars

• injecting the sealant compound into the caps

• distributing the compound inside the caps by spinning

• transfer to molding turret

• forming of the compound by means of a punch (punch geometry, spring pressure, temperature, time)

• ejecting the molded caps

MoLdinG punCH

• fully automatic production process

proCess MonitorinG

• monitoring and control of machine parametersmolding pressure, temperature, and time

• manual or automatic blow-out of caps

HoListiC ControL ConCept

• PLC, servo technology and safety functions are implemen-ted via a single control system (Bosch-Rexroth)

• freely adjustable cap transport

• adjustable starting time and duration of the lining pro-cess

• spinning speed adjustable independently of the lining speed

• deactivation / selective feeding of individual molding stations is possible

fLeXiBLe MaCHine ConCept

• quick tool change due to preset C-frame molding stations

• individual molded shapes by interchangeable molding punches

Processinfeed

• magnetic infeed conveyor

• suction unit for the removal of loose dirt particles such as lacquer threads

• pneumatic stop cylinder for cap separation

LininG

• servo-driven indexing star

• rotating profiled base plates for a uniform lining pattern

• servo-controlled lifting of the caps for precise insertion of the lining compound (optional)

MoLdinG

• continuously rotating turret

• heated stainless steel molding punches

• cam-controlled profiled base plates lift the caps to the fixed molding punch

• base plate, molding punch, and heating are combined in a preset C-frame structure

outfeed

• ejection system by compressed air (blow-out) at outfeed
