Punching apparatus

The present invention discloses a machine for continuously punching holes in a substrate which is to be used in a skin packaging operation. The machine includes a frame which has a punching roll, which is rotatively mounted by the frame and the punching roll includes a cylindrical shell and a cylindrical center roll. The cylindrical shell is provided with a plurality of openings and fitted in these openings are a plurality of punching pins and these pins are backed up on one end by the cylindrical center roll which prevents them from inward movement. The outer surface of the cylindrical shell is swedged tightly around each of the pins where it exits its respective opening and this prevents outward movement of the pins during normal operation of the machine. The outward end of each pin is pointed to perform a punching function. A rubber backup roll is mounted preferably below and parallel to the punching roll. Means are provided for raising and lowering the punching roll relative to the rubber backup roll so that the outward end of the pins may be positioned relative to the rubber backup roll and preferably are at least in contact with the rubber backup roll. Means are provided for rotatively driving the punching roll and the rubber backup roll. Pieces of substrate are fed into the entrance end of the machine and are removed from the exit end of the machine by means of a plurality of belts which are mounted generally horizontal and parallel with each other. The belts are driven by means of first-drive axles which in turn rotatively carry sheaves which in turn carry the belts. The same construction is provided at the exit end to remove the substrate after they have had the holes punched in them by the aforementioned pins. Ejection rollers are mounted at the exit end of the machine and are adapted to engage the upper surface of the increments of substrate to aid in removing the substrate from between the punching roll and the backup roll. Weights are provided for ...

Apparatus for manufacturing a product in membrane or film form for covering sanitary towels or nappies or for filtering systems

An apparatus is described for forming a web (N) that is permeable to liquids and designed to separate two environments and to allow the liquid to flow in one direction from one of said environments to the other, in which said web is caused to pass between two contra-rotating cylinders (5, 7) that are pressed against each other, one of said cylinders (7) having a surface provided with projections which cause perforations in said web (N). The cylinder (7) with the projections is turned at a peripheral speed greater than the peripheral speed of the other cylinder (5), with a consequent relative slipping action between the surfaces of the two cylinders (5, 7).

DRIVE AND BEARING ARRANGEMENT FOR THE CUTTING HEAD OF A CIRCULAR CUTTING MACHINE.

The drive and bearing system is for the cutting head of a circular cutting machine. It has a rotary main shaft with a supporting member for the eccentric shaft on which the disc-shaped knife is mounted, together with a transmission mechanism between the shafts. At the knife end, the knife shaft (5) is supported in a bearing (24) taking radial loads, adjacent to which is a further radial-load and thrust bearing (25,26). The inner and outer races of all bearings are clamped in position so as to allow no free movement in the axial direction.

DRIVER AND STORAGE DEVICE FOR CUTTING HEAD IN A ROTATING CUTTER.

Drive and bearing arrangement for a cutting head of a circular cutting machine

A drive and bearing arrangement for a circular cutting machine is described which is characterized by its high operational reliability, long working life and precise knife guidance. For this purpose a particular bearing arrangement is provided for supporting the knife shaft. The knife shaft is journalled at the knife side via a bearing which is particularly suited to bear radial forces while a bearing unit which can bear both radial forces and also axial forces is provided directly adjacent this bearing. The inner and outer rings of all the bearings are clamped together without play in the axial direction.
