The present disclosure relates to the technical field of punch, in particular, to a real-time control apparatus for punch. The real-time control apparatus of a punch includes an upper seat, a middle seat and a base. Its bottom of the upper seat is provided with a lifting seat connecting with an oil cylinder; the upper seat is provided with a driving mechanism, which connects and drives a slider to move towards the base to close to its bottom dead centre of the slider, the oil cylinder is activated, pushing the lifting seat to raise a H distance, thereby lifting the upper seat the H distance. The slider is also raised the H distance so as to compensate the H distance falling due to the inertia of the slider, so that the slider stops at its bottom dead centre.

Disclosed is a method for making a window in a thin plastic accommodating layer by inserting an insert from a thin plastic supply layer, the method including the following steps: cutting an opening in the accommodating layer according to the shape of the future window, punching the supply layer to produce an insert and inserting the insert into the opening, wherein the punching and at least one first phase of insertion are carried out in a single movement of a single punching and inserting tool, in a direction going from the supply layer to the accommodating layer.

A gripping plate assembly for use in a punch press, wherein the gripping plate assembly comprises a planar gripping plate having an upper front side and a lower side, a first bore extending through the gripping plate, for receiving a tool for use in a punch press. A second bore is arranged through the gripping plate having an overlap with the rectilinear groove-cut at the first side of the articulable tab. A threaded bolt is adjustably received in the second bore. The threaded bold has a head with a sloped sidewall for sliding engagement with the sloped first side of the articulable tab so as to provide a displaceable bias thereaginst during rotative advancement or retraction of the threaded bolt within the second bore, thereby effecting a change in the circularity of the wall of the tool receiving first bore.

The invention relates to a multi-pack container which defines a series of containers (11) formed in a plastic sheet (L) that comprises at least a layer of PET (polyethylene terephthalate), and in which said containers (11) are joined by bridges (12), provided with a pre-cut upper line (13) and a pre-cut lower line (14) for breaking the bridge (12). The pre-cut upper line (13) and a pre-cut lower line (14) are arranged parallel to one another, laterally separated in a horizontal direction and vertically separated to prevent heating by compression and a variation of the properties of the PET layer, allowing for clean breakage of the bridge by rotating the containers with respect to said pre-cut upper and lower lines. The invention also comprises a machine for manufacturing the multi-pack container.
